I have found that this forum software integrates very nicely with WordPress but the default template is, in my opinion, an awful mess of tiny fonts (‘
font-size: 62.5%‘!) and impenetrable
I had made some progress with integrating the design of the fora with that of the rest of the site. Then, I installed BBpress 0.74 over v0.73 and, being a bit dim, lost the changes I had made.
I think the principle benefit of having a forum at the moment is that it presents a less intimidating interface than WordPress.
