Hello, I had trouble originally registering and I was trying to use ErnieMisner as my user name, but I was finally able to register using ErnestMisner. I want to change it back to ErnieMisner but the option to do that says I cannot use ErnieMisner (meaning it is already taken, or?). Not likely that it is already taken, so how can I clear that from the username list or register using ErnieMisner? Thanks.
PS - it's not possible to have a user name with a space in it like Ernie Misner, is it?
