I'm using the iOS version and can not find a tournament that I've joined via the computer. Am I missing something or is that not supported on iPhone?

It can't be done on any phone at this point. Fizzer has said that's something he'd like to implement though.

I have Puffin browser and you can view the entire site on there from iPhone (or any Flash site for that matter). So you can see tournaments, forums, etc. Well worth a couple bucks it costs for the app. It is slightly slower (you would not play games on it over the Warlight app), but gets the job done as a workaround.

I will be switching to android soon, so I can't imagine I will use that browser after that, except on my ipad.
