If it's telling you that the name already exists, then someone already took it.
In order to see if it is avaible, type your desired name at the end of this url:
http://www.gaiaonline.com/profiles/username here
If it redirects you to your own profile, then the name is open and up for grabs.
However, if you get redirected to someone else's profile, than that name and any slight variations of it are taken.
Keep in mind that "username", "USER-NAME", "u S e R n A m E", and other variations of the same letters in the same order all count as one name to the system.
You can just add an extra letter or number to the end though to create a whole "new name" (like "username1" )
I changed my name with hopes of correcting an error in how I originally entered it and tried to change it to the proper name and could not, how long must I wait before I can change it to the name I want? I checked and it is not yet taken and it redirects me to my page still
