I'm looking for a wiki to use with my forum, but can't figure out which one to use. I've used DokuWiki in the past, although it was complicated using authmysql, but can't seem to get it the authentication working with newer versions and I tried MediaWiki but it seems all the smf integration additions are outdated and unsupported.
We use MediaWiki here. There is even a SMF theme for it (like we use here)
Unfortunately I don't know the specifics, as I've never used it myself :(
