I want to use this email for a different COTH profile, will I be able to do that if I delete this account? How do I delete it?
Me, too. I want to delete an old (two years) alter and use that e-mail address for my Secret Santa messages. How does one go about this?
Send a PM to Erin. She will gladly delete alters…especially those used for Secret Santa in the past. Current accounts…well, if you didn’t post a lot under that name, she’ll probably do it. Just ask!
