    IRC (Internet Relay Chat) is a virtual meeting place where people from all over the world can meet and talk; you'll find the whole diversity of human interests, ideas, and issues here, and you'll be able to participate in group discussions on one of the many thousands of IRC channels, on hundreds of IRC networks, or just talk in private to family or friends, wherever they are in the world.

    • Full featured Internet Relay Chat client
    • Clean, practical interface
    • Highly configurable and supports features such as buddy lists
    • Powerful scripting language that can be used both to automate mIRC and to create applications that perform a wide range of functions from network communications to playing games.
