On my machine the box that needs to be filled in has a white background with white text so it's real hard to see that it is in fact filled in. In fact the first time I tried it I thought it wasn't working so I put the avatar in the photostash an linked to it there. Look real close, it may be filled in...
Thanks for pointing that one out. I did a quick fix for that, but its a Firefox issue. Firefox won't let you style that specific type of input box...at least the background color. Looks fine in IE.
