I was wondering is it possible to do the following.

Rather than have all my forums in categorys where you click on a link and it takes you to the forum listing for that particular category.
I wanted Some forums to be displayed on the front page and the ones below that to be categorys and when you click on them it takes you to a room of forums.
Is it possible?

Not without a good amount of work on the files. You want some as sort of "featured" forums, the rest in the catgories... right?

Yeap. How hard would that be?
What files would need to be changed.
