There should be some User rankings. Like a Beginer would be HHR-LS, Next HHR-1LT,HHR-2LT,HHR SS.
Not many but once more HHR special editions come out,You could ad some more rankings!

I think that would be cool. It desnt matter to me, mine always says MODERATOR. I think you can change it on "Edit Options" in your user CP. I can do it, but I am not sure if standard members can.

I cant do that.Oh well.
