to see who is invisible on messenger I use http://detectinvisible.com/
(no 'www' before it. It puts a few cookies from its own url and 2 from someone else onto your pc. But i assume you can reject the non-detectinvisible' ones if you feel like it. If someone techie wants to look at it fine. To work it you put the persons yahoo id in a box and it saying they are off-line or invisible. That's all. jean
