Erm, yea ...as Nairan mentioned - the biggest problem (which is quite a blocker!) right now is that in 2004 SourceForge (where we're hosted) moved from MySQL 3.23 to 4.1 and all of us TreeCastle members are too un-savvy in the database field to succeed in the migration. We've got the sql dump and all, but whatever we do we just can't seem to import it.
Without the database we can't do a thing! As simply as that 
Anyone with MySQL experience willing to help??
It's just databases for PhpBB and ErfurtWiki ...maybe it's a bit more exotic that we used a mod for phpbb with which we were able to attach files (mainly pictures) directly into the database - which means there's also some binary parts in it.
