What will happen to anew user's account if he wishes to change his username after some months in the forum?
If the user has achieved a high rank in the forum, and choses to change his username, will the account be suspected of changing hand and be tagged for that? If yes how will other users know he is still the rightful owner?
You are new enough to this forum to create a new account with a new name. So that's the least of your problems.
