MediaWiki:Common.js

/*
 * Please for the sake of the wiki, please do *some* testing of new Javascript code
 * in your own common.js (Special:MyPage/common.js) before adding them here. As far
 * as possible, avoid adding new stuff here and make your new snippets as a gadget
 * (especially if it requires ResourceLoader).
 *
 * We currently don't have any type of voting to decide what should be here, use
 * common sense whenever possible (e.g Is my snippet going to benefit people?).
 * Talk to the other administrators at #wikimedia-incubator about it first and 
 * get their approval before starting to add code here (make sure it works!).
 *
 * Please add documentation about what each snippet does in the form of comments so
 * that other people will know what each snippet does and would be useful if they
 * are copying to another wiki. Its good to share :)
