100% agree with both suggestions!
The Rate channel (or Rate PkMn?) would be so much easier for newer players to see and use, I never would have guessed to use 'Battle' channel to rate, which not many people use.
Will also give the option to turn it off too, the chat moves so fast, mainly due to rating requests.
Instead of it being a channel you have to 'join' it should be already there tabbed like the Trade/Battle/Help channels.
