I find it hard to believe that you completely forgot your username if you were once active on the forum for some time. Ten years is a long time, sure, but your username? Come on.
It's obvious that's a pure lies, because it's very difficult for someone to forget it's username, what you can forget easily is your password, and you what will make you to forget your password so easy, it's when you don't maintain 1 password or 1 to 3 passwords. USERNAME is embedded in you, because you're the one that created it, except its a situation whereby you're not the one that created the account by yourself, Another thing that will make you to forget yourr username, is when you have a numerous accounts, many alts, it's obvious that you can forget your username.
Maybe you should try to think about it a little more. Maybe it will come to you.
I'm sure that if op think from now till next year, it can't remember the account username, because it's not the one that created the account, any account you build up by yourself, their's nothing can make you to forget about the account, because it's very obvious that you can't forget your name, unless the person have a brain disorder, The only remedy it have memories the account username, is for it, to remember signature campaigns it has applied before, and scroll to the pages of the application, or any context that the account partake on, before it left forum for long time.
