Yeah, on the top left of forums where it says that in tabs, how do I get access to it to add more tabs? Is it hard to do?

Those are applications basically. I'm not sure how you would add another tab but I'd be more interested in being able to choose what appears up there and what appears on like an "applications" bar. Because too many applications and your menu will appear messed up.

You can ask in the Peer-to-Peer forums :). See the notice at the top of this page.
