GREAT FOR SCHOOL
Note: this is in the April fools contest, don't forget to vote
Step 1: Get the program
I've upped it to http://www.megafileupload.com/en/file/56600/FakeSend-zip.html so you don't need an account, but it's free to join codeproject anyway.
Atleast send the creater a thank you note.
Export the exe file in to your favorite folder
Step 2: Making the batch file and running it
FakeSend [sender] [receiver] "message"
the sender can be anything (like GODS_PC)
the receiver can be the name of a real computer, or a * symbol for every computer in the network
the message can be anything
and save it as a .bat file in the same folder as your fakesend.
open the bat file and let the fun begin
