Topic: Intermate.nl
This site has pubBB integrated into the rest of the site. The user login system (or actually the check_cookie() function) is completely rewritten to work with the own login user system. It also has some minor modifications. Other things include some template and module wrapper scripts to work with the site's templates. The path system on top is custom made (it's part of the module/template part and parses before the forum loads). Also the forum block on the site, with recent posts, is custom made.
All to suite our needs. Luckily punBB is written quite simple, so I could adapt it quickly. Thanks for that...
But making a good forum turned out to be too much work, so we decided on a pre-made forum. phpBB is way to heavy and complicated, punBB turned out to be just right.
