Hmm.. let me see. I did deploy a change last night in response to some of the comments below, so it is possible that it messed something up. Thanks for reporting.
I just tried a few basic things and couldn't find anything wrong with the site. Can you be more specific with what is not working for you? Ideally I'd like you to type out the entire sequence of steps it took you to see the problem -- what did you search for, where did you click. Is anyone else having difficulties using the site?
