The Rundown on Winpopup

Ok... I've been using Winpopup on the schools network. Messenger won't work cause the Server farted and stuff....

Now the problem.:D Winpopup gives you the option of sending data to specific computer, or to everyone on the network. Despite my recommendations, people sent it across the network, and they got busted. So I'm guessing this can be read at the server by the Teachers.

What about from computer to computer??

And finally, can you get Winpopup for XP Pro?? I have a network and I need a crappy Chat program to use.

Thanks in Advance.

Also, does anyone know of any documents written by Microsoft on the subject? (Winpopup)

I made a net send program (definently not for school ;) lol of course not, no, surely not, why would i do that?) that can send 1000 messages to everyone at school in a second annonymously.
