Go to the "My Profile" screen and click on "View/Update Profile". You can't change your login name, but you CAN type a new name into the "Publicly Displayed Name". I haven't tried it myself, but maybe that will do the trick?

Yes, it will. It will also change your name on all previous Posts.

I did that once, and had trouble changing back; something about that name already being in use, and probably due to the ghost of the old forums.
