Sir Dude want to play around with my site to see if you can get my board hooked into my mediawiki?
i've actually looked deeper into it and find that mediawiki has tons of features and all that, but for a ubbthreads board, it's overkill.
dokuwiki and pmwiki would be the two choices i'd go with.
and the more i look @ dokuwiki, the better i like it. i much prefer their ACL and just the coding style in general.
the only issue is hooking in the styles in a more automatic way, but any wiki you choose would have that problem.
