I don't know, maybe I am just stupid. But, I had a hard time figuring out how to register. The "Login/Register" button on the top right did not actually have a way to register. Maybe I just couldn't find it. I looked for awhile though. I ended up registering by going to the forums where it told me to register before I can post and it provided a link for me to register.
It is more frustrating then anything. Should be fixed though.
