In trying to delete a bunch of spammers, I accidentally deleted legitimate member accounts. InvisionFree doesn't tell you who you're deleting and I shouldn't have hit the button--it was only supposed to delete the accounts with 0 posts. Instead it deleted everyone from the last 365 days. *smack*
If you need to access your accounts for applications, or to finish up old threads, go ahead and remake your account with your character's names and you should be able to post. Let me know you've done it and I will readjust your accounts.
