I find the chess.com interface very poor. It seems like navigating around is sort of hit or miss, and seems very different between my iphone, ipad and computer.

Every time I click on the tournament tab, it lists upcoming rapid tournaments but never an option to join them.

Why?!

? I've never joined one but I just clicked play, live chess, tournament tab and you can just click on the tournament name, or the join button on the right?
