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!
