/*

To use the script, add the following line to Special:MyPage/common.js
importScript('User:Iceblock/Scripts/Seeking-help.js'); // Linkback: [[User:Iceblock/Scripts/Seeking-help.js]]


 * Documentation: This script adds a tab with information on how
 * many Wikipedians currently are looking for help.
 * Clicking the tab will open Category:Wikipedians_looking_for_help 
 *
 *
 * This script is based on the two scripts
 *
 * http://no.wikipedia.org/wiki/MediaWiki:Gadget-HurtigSlett.js
 * http://en.wikipedia.org/wiki/MediaWiki:Gadget-dropdown-menus.js
 *
 * The function createTab2 is taken from 
 * MediaWiki:Gadget-dropdown-menus.js (called createTab there).
 * It is modified not to include 'mid' and to include 'link'.
 * It is also modified to check the page name and set the class
 * name to 'selected' if the page name matches the category name.
 * The rest of this script is based on MediaWiki:Gadget-HurtigSlett.js
 * and modified to check Category:Wikipedians_looking_for_help
 * Under the Vector skin, it places the tab to the left (!) to ensure it is
 * being displayed on special pages.
 *
 * In the function names, 'qd' is replaced with 'seekinghelp'.
 *
 * An unused function (function displayQuickDelete()) is removed from this script.
 *
