+ * You can set the position of the popup by putting a certain class on the popper.  Use

+ *	Horizontal:

+ *
+ *	Vertical:
+ *		t: top
+ *		c: center
+ *		b: bottom
+ *
+ *	Example:
+ *		elgg-popup-lt-at-rb Puts the popup window's left top corner at the popper's right bottom
+ *		corner.
+ *
+ *	You can set the position of the X and Y offsets by putting the class elgg-popup-offset-XXxYY
+ *	on the popper where XX and YY are the offsets:
