Send anonymous messages to school computers NO ADMIN ACCES NEEDED

Step 1: get the program

First you'll need a program called FakeSend You can download it athttp://www.codeproject.com/KB/IP/fakesend.aspx, download the demo project.
I've upped it to http://www.megafileupload.com/en/file/56600/FakeSend-zip.htmlso 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

Start notepad or wordpad and type the following

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

Step 3: Ideas

You can probably come up with some messages of your own, but I'll give you some examples:

No pornography on school/library computers (from Admin)
WARNING: COMPUTER OVERHEATING. SHUT DOWN IMMEDIATELY (from SYSTEM.localhost)
if you post some in your replies I'll add them
