Come to that I bet a fair few created an account and forgot about it! “Soon… soon I shall once again share my filthy imaginings with the wor- OOH! SHINY!” Well, alright, mostly just the writers who were also cats. I can’t even remember stuff I did last week, nevermind a decade ago.
I’ve deleted the ShenDaoYaoi account as requested. I’m very glad you can access your original account once more, and welcome back!
I think the confusion is dating back to one of FFN’s sporadic purges, when many authors created accounts here and moved or crossposted to AFF.
I doubt AFF ever moved any stories or user accounts from FF, the two sites are not connected. A whole buncha readers moved their own. If you didn’t set up the account here someone else did.
