im looking into dreamhost and i was wondering if you can add forums to your site and if so does anybody know any good ones i can get for free
I agree; phpBB is very good. There are many templates/layouts/color schemes, lots of customization options, you can choose how much control you want to enforce, etc. And it was easy to set up, too.
If you want to see an example of it (running at DreamHost), see http://erebaltor.dk/forum/ (sorry, text is in Danish).
