In my haste to join a game that a friend was starting I misspelled my username. Upon searching the forums I read that it can't be changed. After this game ends would I be able to re register as a new user with it spelled correctly, but still using my same email address?

You are correct in that you can't change it. However, I believe you can take the email off of your current account (using the user control panel in the forums) and set up a new account with your new name. Just make sure nobody has taken that name before...

Also, this is a question. For future reference, post your questions here. http://forums.subterfuge-game.com/viewforum.php?f=10&sid=22548cf308f82859fba2e9f1a367cced

And welcome to Subterfuge! Hope you love the game, and have fun!
