Editor: PIRCH is an alternative IRC client. In many ways, PIRCH is Similar to the standard mIRC client but in a few areas, it is quite different. I like to compare the difference Between mIRC and PIRCH to the difference between Microsoft's Internet Explorer and Netscape's Navigator/Communicator. They both do the same thing, just are slightly different. In case you are wondering, PIRCH stands for Polargeek's (the author's nickname) Internet Relay Chat Hack.
