Update: You can now change your name without losing access to your Faction!
To change your name, go to: https://account.mojang.com/me
Mojang has just started allowing name changes. All servers on CubeBuilders are ready to allow for name changes, except the Factions server. If you change your name, you will lose access to your faction! If you are participating in the Factions server, do not change your name until we tell you its okay to do so!
Thanks for your patience!
