Also, will my current sidebar and header still be used/integrated with this?
It will not override your front page. It will add new pages. When you install it, you can check the Forum Settings page to see the slugs for the pages it will add, and change them as necessary.
I too am having problems
Ive installed bbpress2.2.2 onto my self hosted wordpress site and cant get the forum page integrated, I can use an url redirect but I need a sidebar to show user login/registration.
any assistance ?
