/*
 *	GENERAL JAVASCRIPT HOWTO
 *	----------------------------------------------------
 *	change - changes the background color of the element
 *	j2 - jump to some page (used mostly in the menu)
 *	popUp - create a popup window of specific size
 *	getSize - get window height in pixels (should be cross-browser compliant)
 *	fixBox - used to make the blog iframe follow the browser window size
