I'm in the process of setting up a new website which would greatly benefit from having user-forums.
Since I already have user accounts, and profile details, stored away it seems that I'd benefit from choosing an open-source forum package which I could modify so that logins were tested against my existing database.
Right now all my site is Perl-based, and looking around I don't see many great Perl forums - the only obvious one I could find which is featureful is yabb - but that is written to authenticate against flat files and to be frank the code is nasty.
If I need to use a PHP solution then so be it, but first are there any simple forums that are written in perl that you'd suggest? I'd expect to have different forum-groups and nominate particular users as moderators. More than that I don't need, just basic threading and an attractive appearance.
