bbpress should already match your site’s look and feel if you have installed bbPress plugin for WordPress. bbPress ships with a TwentyTen child theme which is used to lay out the bbPress pages within the wrapper of your active theme (if the active theme is not already bbPress-supporting)
I’ve been following the development of Thematic for the last few months now, which makes it pretty lame that I’ve never checked out the forums until now. Looks like a great community/resource from what I’ve been able to tell over the last few hours.Anyways, I’ve just released my first Thematic specific Child Theme called Boumatic. My main goal with the design was to step away from the default Top Header, Left Content, Right Sidebar layout that comes as the default. Check it out and let me know what you think!
