Re: getting forum to show up on wordpress page
It is probably less work to use bbPress than using other forum software if your intention is to re-skin to match your blog. You can actually “load” WordPress inside bbPress (check the documentation), but there is a definite performance penalty in doing that.
The best performance choice is to integrate your user tables and auth cookies. Then skin your forum to match your blog, but don’t “load” WordPress into bbPress unless you intend to use WordPress functions inside bbPress quite extensively.
You will probably find the exercise of skinning your bbPress install quite simple compared to other forum software. The templating system is similar to WordPress, so it will be a familiar environment if you have done that before.
