I can only try to recover a site if you give me messages like this:
Your Nabble site "In and Between the Lines" has been deleted.
You can download a backup of this site from the link below.
Nabble will try to keep this backup available for a few months, but this is not guaranteed.
If this content is important to you, save this copy as soon as possible.
I tried to restore these forums, but they were probably deleted a long time ago.
We don't have the backup on the server anymore, so there isn't much we can do at this point.
