How do I get rid of this bar?
 

I wonder if it's a new feature. I see it also has a chat room feature and all.

There may be a way to disable it completely. It's very new, so just give it some time. Even if you close it and there's a little icon, it's small and out of the way so it's no big deal.

The bit at the right end says "close this bar" when you mouse over it :)

@jellysundae: I already know about that. But I was talking about a way to disable the feature.
