John,

I've finished filtering on the homepage. It's not the nicest-looking implementation, but it's some pretty sweet functionality. I've now removed the "reload" button, as it's basically moot. Check out the files I changed if you want to see how I implemented the ajax calls, I modelled all the stuff after what Stephen did. Please let me know if you have any questions. Also, we're gonna need to remove the "user-defined" tag at some point, I might do that next.
