I was just commenting to someone as to how confusing that site is. There's a box next to the "JOIN" / "SIGN IN" words in the upper right, that is positioned next to those words (as if those words are the label for the text box).
So you start to key in your name, to join, and a bunch of choices are displayed. If you select one (even your own), you are whisked away to another page that isn't even the join / sign in part of the site. You are no closer to being signed in than you were before. And actually further than if you had clicked on the label for the text box that says "sign in" (which is actually a button or a link, although not identified as such, unless you happen to mouse over it).
Ends up the "join / sign in" text box is actually a SEARCH text box.
yeah, real simplified. Put the word "search" in there. geesh.
