Hello tasu.
You cannot change your name freely. You can only change it completely when you retire (Going from level 31 or higher back to level 1 - gaining 1 generation and loompoint(s) ).
With the Name Change funtion you can only add/remove clan tags. So if you are named "tasu" at the moment, you cannot change it to "blowchicken123" with this function. You would have to retire.
All Name Changes are accepted or declined manually by the admins, so there is no way to cheat here.
Greets,
Chris
