Re: Forum not displaying in the topmenu?
The bbpress forum install isn’t part of the admin menu. You can put it there by modifying the menu though. I’m guessing that the second question means that you’d like your bbpress theme to look like your bp theme. Yes, you can. You have to create a new bbpress theme for yourself.
You can find or create any theme you want for bp and bbpress. There isn’t a bbpress theme that looks like the default bp theme yet. As far as I know.
