When I went to log on, since the same form is used for logging in and creating accounts, and since I regularly use multiple email addresses for different purposes, I accidentally created a new account with my personal email address as the username.
Since I do not want webcrawlers etc to be able to find that email, I would like to either delete the new account or to change its username.
I have not played any games on the new account so there shouldn’t be any problems with that.
