Here's the mail I recieved
The SW Combine Administration has declined your membership application providing the following reason :
Your handle does not match our current rules requirements. It was turned down because it either contains numbers/special characters or it doesn't sound like a name (ie: Red Wolf). Please refer to the Character Creation rules page located at http://rules.swcombine.com/character/charactercreation/ for more information.
Please make the necessary changes and try again. If you have any questions or queries feel free to post on the post on the Problem Centre
