// @name		Yahoo Mail Username Assistant
// @description		provides a drop-list of yahoo mail login names.
// @include		*mail.yahoo.com*
// @include		*login.yahoo.com*
// ===/UserScript===
//
// In answer to a request on the wiki, this script
// saves a clickable list of yahoo usernames to select
// from on the login page. Any time a new name is used,
// it gets automatically added to the list, so to start
// the list, you have to type in the first name. Remembers
// the last username used and automatically populates the 
// input box with it. There's probably a simple way to 
// re-enable the browser's native form-remembering, 
// but this way is more fun.
//

// Complaints: cwf [] axlotl [] net
//
// Clear the list by uncommenting the first line
// and loading mail.yahoo.com once.
