Hi!
One of the issues might be that your email client is Microsoft’s Hotmail. After the data breach last year, Microsoft made some changes and the end result is that our archive code doesn’t play well with Hotmail, Outlook, or Live.com email clients. We’ve had success doing a temporary change of email to a gmail account, which does work with our activation and reset confirmation emails. Once you have successfully reactivated the account, you can always change the email address back.
If you want to try with a different email address, I would strongly recommend you send that to us via our staff email: tos_team@adult-fanfiction.org. Spambots can and do harvest email addresses from public forum boards, and no one likes spam emails.
As far as the fields, the only one that’s particularly specific is the birthdate field. The format requires a 4-digit year, a 2-digit month, and a 2-digit day, all separated by dashes. As an example, if your birthday was July 11, 1986, you would enter that as 1986-07-11. Pen names and names now require an underscore between words, so you would enter your pen name as Teris_Xenite.
I hope that helps!
