delete/D topics

Dear "supporters" and nabble forumers,
if me, or one of the registered users of my forum, writes a new topic and then, immediately delete it, will this deletion and the related topic be sent to every registered user and so on? Will everybody know about the deletion and also about the deleted content? Many thanks in advance to everybody! GdA |

If a message is deleted it will immediately be removed from the forum. Subscribers may still receive a copy of the message.
My understanding is that a Nabble's servers are scanned for new posts repeatedly. The timing and duration of the scan will vary slightly depending on other activity on the server - the number of posts coming in, numbers of posts being served to people viewing them, and so on, how many using are requesting full archives of their forum be generated, etc. As they are found the new posts will be placed in a queue and once the scan of the server is complete that batch of new mail is despatched and the process starts again. The scan may last in seconds or minutes, depending on how busy the server is. So it is possible that a post will be scanned and placed in the mail queue in the few seconds before the post is deleted. Once in the mail queue subscribers will receive a copy and have access to a post that may only have been available on the forum for a few seconds. In that case, subscribers will have the copy of the original message and will be able to reply to it and quote its entire contents. Of course, one must assume a subscriber is unaware of what is happening on the forum and they will have no knowledge that the original post has been deleted so it can't be assumed that re-posting a deleted message is in any way a malicious act. Moral: whether posting via the forum or by mail never hit the POST MESSAGE or SEND button until you are certain you don't mind your message haunting you for the rest of your life! (Been there! Done it!)

Thanks a lot Greg for your clarification...
of course one should be absolutely sure when deciding to send or not a message...obviously somebody could do the wrong thing anyway... last week one of my subscribers posted a new topic and then it was immediately deleted...I, even I'm the only admin, didn't receive any trace of this deletion on my mail...I only knew he deleted this message going the forum on the site. Yesterday happend the same from another user...but I received an email containing the deleted post and when I went on the forum site there were no sign of the deletion. So, it doesn't seem a matter of server but a matter of "selected options" ?! And... what if I, being the admin, decide to delete my, or the post of a member...will everybody know this? or only me and that person? thanks in advance! |

There's a little more to it that I explained in my previous and I can't tell if the following applies in this case as there's not enough to go on. You don't say why/how you "only knew he deleted this message going the forum on the site", so I'm guessing... You had a mail that was a response to the deleted forum post and that is what prompted to visit the forum, where you saw the original message marked "Contents deleted" with the reply under it. When a user deletes a message it will no longer appear on the forum UNLESS someone has replied to it. For the Nabble's "universal back-end" system to work, a reply needs a "parent" message. If the original message has been deleted a "placeholder" for that parent will appear indicating that the original message contents are no longer available. You are specific, saying a "subscriber" posted the original message. That means the original post was made by email, but it would only be deleted by a visit to the forum. That implies a whole range of cycles of server activity were involved. Apart from the scanning for new topics I referred to earlier to place messages in a queue to be sent and then the process to despatch the messages in the queue, there will a constant cycle of other house-keeping tasks taking place on the server, one of which will handle incoming mail and converting them into forum posts, not to mention the apparently simultaneous processes of handling posts being made on the many forums handled by the server. Some of these processes will be placed on hold for a brief period while other higher priority tasks take place. I'll have to come up with another theory if you tell me my guesses are wrong! I suspect that in this case, there was no reply made before the message was deleted - but you got the mailed form as the scan for new posts took place a few seconds before the post was deleted. I don't think it's a case of user selectable "options". It's all a matter of the exact timing of the post and deletion and what precise house-keeping activities were going on on the server between those two points. When a post is deleted (whether by a forum admin or the author) the author is sent a copy, so the author will always know their post has gone. As to who else knows, all the above applies, so that will depend on how many subscribers there are, and the order of events at the server in any particular case of deletion.

Hallo Greg!
Thanks a lot for yor reply in details! I had to "study" about your suggestions and guesses and...you are right! There is a difference in the two messages I was talking about and it is just as you told me, the first had a reply and the second had no replies. Everything is more clear now... :) anyway, considering the "queue system" you explained, why "Nabble" doesn't restrict the possibility to know about the deletion of a topic only to the admin and the person who wants to delete it? Furthermore, just few minutes ago, one the new registered users asked me to cancel her registration to the site (she wants to make a new one with a more private mail and nick) I looked on the profile and I can only Add/Remove Groups send email to or ban this user what should/could I do for her now? Many thanks! |

Glad I got it right this time. I don't always do. Does that mean that you want to stop the ability to subscribe to a forum? How long should Nabble hang on to subscriber mail before despatching it? Perhaps you are only thinking of your concern is about the immediately recognised "mistaken" post someone wants withdrawn. But what about those who only recognise their "mistake" once the flame war starts, hours or days after the initial post? Others forum admin will be more concerned about that scenario. How long a delay is reasonable before it makes a mail subscription so slow as to be unusable for the purpose of that particular forum. Not everyone find daily digests acceptable, some might find even a few minutes too long a delay. In short, it really is a tricky one and I don't believe their is a simple answer that doesn't seriously damage the usefulness of the Nabble service for a significant number of other users. She can simply change her own username or email address so there is no need for a new registration. First she clicks on her username at the top right of the forum and follows the options: Account settings > Edit Personal Information > Change email Account settings > Edit Personal Information > Your Username However, changing email on privacy grounds, is a bit pointless as apart from to the forum admin an email address is completely private as Nabble munges any email address, even on subscribers email, Only the forum admin can know a user's true email address.

Hi Greg! No Absolutely not Greg! Idon't want to stop the ability to subscribe to a forum ;)...but "simply" avoid to let all the other "readers" to know about the content af a deleted topic. I'd only like to make the process "more private" enabling to obvously know about the fact the admin and the person who did it. Why wouldn't that be fine?! :)
