Giving my feedback about the big things I care about: The biggest problem I see is that you have no HTTPS support for this site. There are very good reasons for having HTTPS even if you aren't transmitting something you would consider "secret". With modern 64-bit processors and session caching, there's really no excuse for not having HTTPS available on every page. That said, you don't even have HTTPS support during login, which means that password information will be completely sniffable. It's not at all clear from the login popup that this will be the case. Additionally, the actually design degrades nicely with Javascript turned off, which is commendable, but logging in/signing up is still Javascript-only. Ideally you'd want a site that keeps all the functionality that it can have without Javascript with Javascript enabled. It might look slick for people using Javascript, but you really don't need an in-tab popup for login/signup.
