troyronaldson:
and whats the reason for that icon?
I think I already mentioned that there are several. I personally don't know which one is main and if it's just our policy but my own guess is that's done because many people develop reputation within a community, good or bad, so if they were allowed to change names on the fly, it would be impossible to track it.
when you actually close the account to start new, the account name stays locked, so no one else can have it.
