I have a forum user with an email address at gmx.net who had difficulty registering to the nabble associated mailing-list (lists.openscad.org).  i.e. his forum posts were flagged 'This post has NOT been accepted by the mailing list yet'

This sounds as if your forum user has not subscribed to the main list for which Nabble provides an archive.

You need to be aware that, in essence, Nabble is just another subscriber to the main mail list. The messages that it receives via its subscription are then automatically posted to the Nabble forum.

People who subscribe at the Nabble forum are simply asking to receive all the posts that Nabble receives, but that does nothing to subscribe them at the mail list itself.

People who register and post at Nabble, simply post to the Nabble forum. Nabble does forward those posts to the mail list, spoofing the original posters address - if it didn't spoof the address then every Nabble poster's post would become a post by Nabble itself and the original author's email address would get lost). However, 99.9% of mail list servers will only accept posts from its own subscribers.

If Nabble receives a rejection message from the mail list server, it then adds the "Pending" warning on the message in its forum that you describe. The Nabble subscriber MUST also subscribe to the mail list itself.

Unfortunately, the text that Nabble supplies by default at the top of any mail list archive page is a little confusing, if you are not aware of the difference between the archive and the list itself.

At http://forum.openscad.org/ it says:

========================
OpenSCAD
This forum is an archive for the mailing list [e-mail] (more options) Messages posted here will be sent to this mailing list.
Messages posted here will be sent to this mailing list if you have subscribed. This mailing list is a discussion forum for OpenSCAD users.
========================

The links take you to a page that allows you to subscribe to the mail list itself and perform other options. For example, it allows you to suspend your subscription to the mail list itself which is useful if you plan always to read and post via the archive.

I will suggest to Nabble that they change the standard wording to something like this:

This forum is an archive of messages posted to the mailing list [e-mail].
Messages posted at this forum will be forwarded to the mailing list, however, they are likely to be rejected if the poster has not subscribed to the list itself and will show here as "pending".
