This is actually the first question I answered.  It involves using the doodle IMVironment and sending a request.  IM the person or buzz them, then quickly access the doodle IMVironment.  After a period of time, up to one minute, if the screen goes blank and allows you to draw, then they are online.  However, if it says blah blah blah unavailable...blah yack yack....then they are offline.

Maybe, maybe not.  He might be in stealth mode.  When I log on, my messanger logs me in as invisible.  Why don't you just ask him.

People usually uses the Invisible to stop annoying IM's. They are usually online. Send them and IM and  and it will tell you if they are online or not.

Just add your friends on your list, and if whoever is online would appear online, otherwise they would appear offline. Bear in mind that some users can use the stealth settings which allow to appear offline.

if you go into invisible mode, you can see who all are invisible. but if your friend has put you into invisible mode then you won't be able to see.

uh most online can hide behind a computer.  a background check will only pull up details on his past...doesnt tell you who he is today.  \n\nemma____@yahoo.com\nNorthwest Investigation

If you didnt empty your trash folder check and see if they are in there. If not, I'm sorry , I'm afraid they are lost in cyberspace forever!

You can't. That's the whole point of invisible mode. It's so that no one can see that you are online.
