Hi, I currently have a dropdown box on my site http://www.horrorexpress.com that I use to change skins. I basically attach the skin variable (it's a PHP site) to the end of the URL manually (in what now seems a very ugly way).
I've been doing it this way for months, but now I'm switching to SE Friendly URL's this way will no longer be possible. Also it will help to clear up pages in my Search Engine results.

So basically I guess I want to use Javascript to POST the variable (skin name) I need sending, so that it doesn't change the URL or Page?

I know next to nothing about Javascript, so I really would appreciate any help from someone who does.
Thanks.
