theymos can change it to Anonymous. Maybe
Cyrus can do it too.
Deleting accounts doesn't mess up any threads, like
this thread. It just changes to anonymous, with no profile information. Post stays intact.
As you can see here, I only change the username to "Anonymous" on request.
I guess both can doing that and changing any other Username also !
But there is a little trick with that Anonymous Username feat. when it was changed .
If the Topic or the post was edited once from the Account you can hover with the mouse over the Date and it shows you the real Username of the Account !
