I've got one invite if you or somebody you know needs one. You can PM me if you don't want to give email addresses in comments.

I've made two little Stylish styles you may find useful:
-- one to switch all font faces to sans-serif (this won't assign a specific font, just switch to your browser's default sans-serif one). It's here.
-- and another one to restore the background color for relationships the archive used to have. I use it to make it easier to spot het/slash fics as opposed to gen/friendship fics, and the listed pairing(s) of the fic. It's here.

Note: Stylish is a Mozilla Firefox extension but it can also work with Google Chrome. Installation instructions are here.

(Dear admins, I didn't know what tag system you wanted to use so I've left tagging to you. :)
