Create a new "Super Administrator" user in joomla 2.5 using MySQL

	1) Go to the joomla database
		# e.g.	use myjoomla

	2) find a free ID - default admin ID is "42"

		SELECT id from jos_users;

	3) create a new user in table 'jos_users': 

	        INSERT INTO jos_users values (100,' newadmin','newadmin','','531b5f50f082c59730b3bf7f9c457129:GA8lZqlJVZQbD8GYFGltJGNNIvjmcRcT','Super Administrator',0,1,'','',1,'');	

		# ID=100	--> a free ID
		# 531b5f50f082c59730b3bf7f9c457129:GA8lZqlJVZQbD8GYFGltJGNNIvjmcRcT is the salted hash for the secure password '123' ;)
		# feel free to change the password afterwards by WebGUI!

		INSERT INTO jos_user_usergroup_map values (100,8);		

		# again, '100' is the free ID
		# '8' is the value for Super Admins

	*) UNDO
		DELETE FROM jos_user_usergroup_map where aro_id=100;
		DELETE FROM jos_users where id=100;
