// This script displays, crudely, at the top of the page,
// the ratio of users in the current thread whose user
// number is below yours. For example, a rating of 95%
// means 95% of posters in the thread are more established
// MeFi users than you. You should bow down to their inherent
// superiority until another 10,000 or so users sign up and
// you feel like less of a noob.
