Long answer is, you need to complete 250 quests and then contact an admin, give them a list of preferred usernames and they'll change it to the first one that's available
@porwmenos Like Doombreed stated, if you have a total of 250 Quests or more you can email me directly ( MrDayCee@armorgames.com ). Please add the new username you would like, as well as a second and third option in case the first and/or second are already in use, ok?
