// @description    Uncheck a login form checkbox and focus on submit button
// @version        1.1
// @include        http://userscripts.org/login
// ==/UserScript==

// Please make copies of this code, give it to your friends, change it,
//   modify it, steal it, rewrite it, use as you wish.
// But if you make money off it then I want half.
// ---- Notes ----
// For the sake of ultimate redundancy...
// This script can work on any login form with a checkbox,
//  it will find the first login box checkbox and uncheck it
//  it will focus on the submit button
//  if you change the password it will show in a tooltip
// If it does not find the correct box you can define
//  the checkbox name for any domain, see below
// You can also disable it and just use it to focus on the button,
//  just use "none" after the domain name, see below.

// ---- Options ----
// Name of box to uncheck or "none" to skip
//    - use this if there's more than one checkbox
// List format "domain1": "inputname1", "domain2": "inputname2"
// www.userscripts.org redirects so this example actually does nothing
var checkboxName = {"www.userscripts.org": "remember_me", "example.com": "none"};
