Seriously, though, has vBulletin been considered as software? It is used at www.tivocommunity.com that is about the same size and never experiences trouble like this. They used to use ubb, but changed. You can talk to David Bott who runs the whole thing (base forums are at www.avsforums.com, of which tivocommunity.com is a sub-board)
