What will happen to anew user's account if he wishes to change his username after some months in the forum?
It must be a special case with very solid reasons, and must get an approval from theymos.
Done. Now only moderators, Donators, and VIP members can change their names automatically. Other members should contact me. I'll probably ignore your request if you have less than 50 posts (unless your posts are very good).
You can't. You can try PM an admin and they may do it, but they usually don't. You can just create another account with that name if you feel like you need it.
