I've been tired from searching for a web service or and application neither script to let me detect who has signed in appearing offline into any of those versions of Windows Live Messenger (8.0,8.1,8.5 Beta 1)
All the web services that provide this feature are (servers down) all the time.
so can somebody help with this ?
This is not really possible, the reason of it is a breach of privacy, therefore the Windows Live Messenger protocol is made in a way to forbid that kind of intrustion.
Think about it for a second, what would be the point of appearing offline, if people could know we're online?
Yes,dear..I know it was silly even while I was posting the thread I didn't hold much hope.But asked myself: "Why not trying?"
thanx alot you've rolled my mind back.
