for the person who is unaware on what to do during these times this is what you're supposed to do. (from what I can remember)
you email the GM staff (usually the Head GM at the time) with as much information as possible as to when the account was created.
You should probably include what you think is the email that is tied to the account.
You should include the location (state / country / city) you were in when you created the account.
Might want to include the time more or less when you made the character on the account or when you registered
