Not Used: Player activated name change option

I saw this on another server....been a long time and i cant remember...but you had an option of buying a token(fora large amount of coin) and could then retalk to same npc and ask for a name change. The game then *listened* to your next text in the gm channel....and changed your name on the database and your character file to whatever.

It allowed knights and stuff to put *Sir* in thier name and what not. Im not sure how it was implemented or if you can do it ad but it would be a cool option as i reallllllly want to fix Unions name.
