I don't seem to be able to change my name. I went to "My Account" but I am unable to type anything in the "Username" box, which is shaded and shows my current name. The box for my email is white and it appears that I can edit it.
I also don't seem to be able to send pms. I just noticed one this evening that had been sent last week. I want to reply reply and apologize for not doing it earlier. I was able to type it up, but when I hit "send" nothing happens.
