First you will need to create a second account with a wacky name (No racism or offensive/religious names please)
E-mails are recommended to be fake. Write off a random password that you do NOT use.
After creating the game account, send a mail to GameMaster with the title: Player: <NameOfYourAccount>
Inside, include your password to said account.
Before submitting, make sure you've made the user hidden/invisible from Profile > Prefferences!
Upon entering a game, you will be given one of those account's details. That way nobody will know who you are.
