I accidentally wound up with my email address as my screen name. I went to edit my profile, but changing the screen name isn't allowed. I tried creating a new profile with a new screen name but it won't let me use my email address. I created the new profile using a different email address (one I keep for junk like this, so I don't check it and therefore, isn't what I want to use for this). I also don't see a way to delete a registration. If I could delete my other profile, I could then just recreate it with the new screen name. How do I fix this since your site isn't properly programmed to allow me to fix this?
