I'm the administrator of userstyles.org. I want to start offering my styles to Greasemonkey (and similar) users. For applicable styles on userstyles.org, just plunk "/style.user.js" at the end of the URL. (For example, http://userstyles.org/style/show/242/style.user.js ).

I'd like some feedback on the format I'm using. Is the code the best it can be, are there problems with meta-data, etc. Thanks.
