Glitch during sign up?

This app has some interesting content. However, I believe there is some sort of glitch in the signup screen. I entered my email address, password, and a screen name, assuming that my screen name would be displayed when I commented on articles. Imagine my surprise when it was my email address that was displayed instead! Huh?? I sent a request for help to the suggestion link but of course Ive heard nothing. And theres no one to contact about this type of problem. Im moving on and would recommend that you do too. Disappointing....
