Be aware that any script like that can be used against you to get you flooded off the network over and over until you get banned. It just takes a few people typing that multiple times and you'll be replying over and over and over. If you absolutely must have such a script (I don't recommend it), you should at least put in some protections to avoid that problem.

Scripts go in Remotes - (Alt-R)
