BuddyPress.org

I’ve incorporated Buddypress into an existing WordPress installation. I am hoping to have both users who post blog entries with members who post in forums like this. Is there a way of giving some Buddypress members the privilege of posting on the blog?

I’ve tried to find some guide as to the relation between back-end users, found only on the dashboard, and buddypress members in the forums. Nothing has come up yet. It would be good to understand how they are related.

I am hoping that all the WP users can be also Buddypress members – do they need to register twice for this?

Thanks for the advice.
