I tried to change mine to my full name and couldn't. I just used MIke at first to sign-up thinking I could change it. But I put my full name on my signature and profile. I can understand hiding your email maybe because you are doing it from work, but not otherwise. As Chris wll knows, there was an incident where someone (although he did identify himself) mocked Chris on another group and that person was quickly and unceremoniously removed with no recourse, which is as it should be.
