You would have to contact staff about that I believe. Shoot Frost or Dynamo a PM and they should help you!
Have you checked the email? You could hit 'forgot password' and have it send the info to that email and then just remake the password later.
You're welcome, hope it works for ya!
I did that but I know my password I just don't know the UN because I used fancy letters ):
That's fine! When you go to login you'll see 'forgot password' and it'll prompt you to put either your username OR email there. Then it'll send you an email which'll hopefully have your full username listed on it for you to use.
Could you drop the link of the other account here? We'll get it sorted out somehow! ;)
stupid me for using fancy letters back in the day 
It's this account https://feralfront.com/index.php?action=profile;u=181263
Can't do anything about it except change the username. There was a database glitch that glitched out some non-standard letters, so some things "fancy" got glitched. Can you PM me and confirm the email in the PM, as well as telling me what you want your new log in (username) to be?
