Alright, I have gone ahead and given SGMonkey a backup of the complete SHOTN-forum. That may be a somewhat unauthorized step on my part, but I think we should take this chance, while we can.
The way it looks SGMonkey will try to create a collective superforum containing the forums for S'HOTN and all of the projects on project-tamriel as subforums that can still act as individual forums, but with a common login for all members across all projects. That seems to be the idea so far, at least. I hope it will work out.
