Operation temporarily unavailable. WHY!?!?!?!

dance210:   Hi!   As Cent said, you can try a different browser window or wait a bit and come back later. You can also try Ctrl+R to force reload the page. If that doesn't work, feel free to email tournaments@wargamingamerica.com with the name of the team you are trying to join and your in-game name.   The error normally seems to pop up when the page is trying to refresh date (e.g. especially when it's calculating match scores), although it happens other times. It also seems to have a long cache, which is why the reload will sometimes work.   Good luck!
