confused about signup-username,etc

[airbrush]

hey yalll
  when I signed up, the registration said to use my "real name" as my user name, I did so, then went
into the "my profile" part of the site to change my username to "airbrush" , However whenever I
try to log in, only my real name is accepted, yet "airbrush " is used in the message notification of the forum pages (top right area).
  And I keep getting "News: you need to login to your account," heh even while I'm already logged in.
   I would like to keep "airbrush" as my user name, and will continue to login with my "real" name for now.

By the way Robert, I'm glad you decided to start a site, heh I've tried to look up and download most all of the posts by you, Mr Francher, and Mr Rabe, I think you build some of the "purdiest" airplanes
I have ever seen.
   thank you
  airbrush.

Your real name is you user name and airbrush is you display name this is what people see. Only you and I see your real name.
