Hi I have a couple sites that are nothing but forums...so the homepage is the forum. Without any additional SEO hacks, is one better than the other? From what I can tell, vBulletin gets better results than any other message boards.
vBulletin absolutely destroys phpbb when in stock form, but phpbb is great if you install this (highly recommended): phpbb search engine optimization mod
I'm getting much more pages indexed by using vB. Used both several times and after comparison I would tend to recommend vB or even better vB SEO
Awhile ago there was a worm that used google to search for phpbb forums because an exploit allowed the worm to defaced them. Thousands of forums were defaced in a matter of a few hours. After that the keyword "phpbb" itself was banned for a few months. With such a "rich" history I think I'll pass phpbb
I still prefer myBB over phpBB And i'd still use it over vB, simply because I can't be bothered to pay that much for a forum when free alternatives are available, that do pretty much the same job. And I can still customise it all I want
