So, I rejoined MyM after probably about 6 months (or more not sure) hiatus from minecraft and I cant do anything at all. I reread and reaccepted the rules but it still won't let me do anything, cant leave the spawn building Edit: just tried in the lobby when the server restarted and I cant seem to fo anything there either.
Please try if you have the same issue on a other server and also try to connect with vanilla 1.6.4 to the lobby.
