OK, as you may know on an Invision forum only Admin's can change your username (unlike Proboards). If you are requesting a name change you must remeber that when your name gets changed you will have to login with that chosen name. (e.g. Say "Fred" wants to be called "Rodney" from now on he will have to login with "Rodney").
Rules
You must wait 48 hours after a name change to be eligible to request a new one. This is not to be strict but rather a way to to stop abuse.
I also recomend you choose something without special characters (e.g no "© ® ™") as it will be difficult for you to login and also send/recieve personal messages.
Request away!
