I am a big fan of ppBress and now use it as my forum of choice. I love how it now integrates perfectly with WordPress, it’s simple to use and well placed for hobby bloggers who want to run small forums.
I even migrated a site that used the commercial vBulletin software over to bbPress – you can read that story here.
bbPress Guide Book
The official bbPress site is currently linking to this guide so I thought it was worth a mention here too. I’m afraid I have not read it so I can’t give a personal recommendation but if you need some extra information on how to run a bbPress forum then this looks like your best choice right now.You might be interested in:
