The current problem is with admins doing so many shiftname (permissions to use changename for free) and also admins having to search logs because you FORGOT what you changed to!
For one thing, newbies ask in /p first how they have to change their name. Then it's usually a regular player explaining to them how the system works and not an admin.
Secondly, 'admins having to search logs because you forgot what you changed it to'? How many times has that happened? Twice? Just cuz there's a topic on the forums about it, doesn't make me believe this happens on a regular basis.
The first nickname I joined with was crap and I'm sure you'll have a lot of newbies being unhappy about their nickname and the fact they can't change it in to something else. This leads in to more multi-accounting, which means more work for you guys to do.
Face it, this is (in you language CBF) BOLLOX!
