Dear all,

I would like to set up a community blog as follows:

– anyone may register and post to the main and only blog under certain categories
– after posting, the post shall be approved by the moderator

Here are my questions:

– is it possible to do so with BP?
– shall I install WordPress-MU? Or single WP will do? Once again, I need only one blog. I do not need visitors to set up their OWN blogs, they shall post in the one main blog.
– what is the interface for posting for visitors? Standard WP admin panel? Or it can be intergrated in the blog design w/o any difficulties?

Any links to tutorials, explanations etc. are highly appreciated.

Thank you very much!
