Could I Get My Old Username Back ?

[greytraveler]

Hallo  
Recently I reregisted using a new spelling - Greytraveler (one l instead of 2 ll). The reason was because I could not logon. I had misplaced the old password and had a new email address.
So could I some get the old username back. That is Greytraveller with 2 ll.
Any help you could provide would be appreciated.
Thanx
