We're on the same software as before, actually. The big issue with restoring the database to the old one is that I don't have direct access to a MySQL admin software and also only a single database anyway. Additionally, over the years the thing has become bogged down from server change after server change and there's a lot of mix mashed data in it from old stuff like the switch from phpBB to SMF, and the addition of that crappy portal.
I'll see if I can setup an archival version on here, possibly in text-only mode or something. Otherwise, I'll take the database backups and remove anything that isn't the post array and put it up and maybe someone can make a nice page for it, kinda like the older Lemmings Forums.
