Anyone know any old or dead GPL forum php software? as in old projects i can take over?

I know there were several forum scripts for sale (and at the moment I only know Ekinboard (http://www.ekinboard.com/forums/v1/viewtopic.php?id=419) is) but for the others you should better ask/check at http://foruminsider.com/forums .

Plenty of projects to be had at the o'l forge (http://www.sf.net).
