I found it through www.sevengraff.com. I use the NLB script for weblogs and noticed he uses minibb for his forum.

I found it by searching Google for "open source bulletin board"

I found it on www.framasoft.net. It is a site where you can find lots of free and open source things.

Found it on http://php.resourceindex.com/Complete_Scripts/Bulletin_Board_Message_S ystems/. It was one of three high ranked scripts I downloaded to try out. Could't use one cause wrong version php. Liked mini best of the two I did get running.
Only quibble with both of them: I use Dreamweaver template pages for the ease of updating and so clients can use Contribute to update reg content. I love to find scripts that don't insist on their own headers and footers and will work within other pages. Ended up sticking mini in an iframe. Good work though!

Founf it on hotscripts.com
