How do I make sub-forum posts part of parent forum?
 

If I have say 4 child forums, how can I set it up so all those posts are all listed in the parent forum?

Say I have a main "Team" forum, and child forums: pictures, videos, chat, news.

Only pictures go into pictures, only chit-chat into chat, etc..

But if the user is only in the parent "Team" forum, ALL the threads (of the 4 child forums) are listed there.

???
