Didn't you mean that? Have news as a child board of Andy Murray? Or you meant as a big category. Problem with that is it can make the page too big so you have to scroll to see whether there are new posts for certain sections.
Umm... I thought it was fairly clear in my post.
Two categories, Andy Murray and Murraysworld Community.
Andy Murray to contain the boards News, Murray Chat (or whatever... the current Andy Murray board), and Main Content.
Murraysworld Community Category to have Chit Chat (with subforums), Introductions, Photos etc.
I don't see how it would make the page too big?
It would only be the same or smaller than it is now...
