One of the rules we have is that your account name must match your character's name. Not everyone realizes this when registering their accounts, so we end up with mis-matches. This is not a huge problem, it's a very simple fix that only takes a few moments.
Anyone in need of a name change that can't find an admin right away, leave a note here with the name you need your account changed too. Just remember, the new name becomes what you log in with, so make sure to adjust saved auto-fill data for your log in accordingly.
