// ADVANCED AUTOMATICALLY REFRESHING RECENT CHANGES AND WATCHLIST JAVASCRIPT // Code courtesy of "pcj" of WoWWiki. // Source: http://www.wikia.com/wiki/User:Kirkburn/global.js

// INDIVIDUAL USE // This is a modified version of the WoWWiki site-wide version (from http://www.wowwiki.com/User:Pcj/ajaxrc.js) // This version is designed for Special:Mypage/global.js use.

// WIKI-WIDE USE // If you add it to a wiki's MediaWiki:Common.js it *should* work - however, this is untested. // It should not conflict with your own global.js (though you will see two tickboxes)

// WHAT IT DOES // The code adds a checkbox at the top of Special:RecentChanges and Special:Watchlist, next to the header. // Ticking this sets a cookie (specific to each wiki) and starts updating the list. // This occurs silently every 60 seconds without a full page reload occurring.
