For those of you that don't know, there is a site called Bugmenot.com that provides logins for stupid sites that require compulsory user registration (such as the new york times, etc.). I created a little javascript that will popup a window with an username and password for the site, or an entry to add one to the list if it doesn't exist in their database.
To use this javascript, just drag the following link to your links bar: popup bugmenot.com login
Enjoy.
