mIRC is a highly configurable IRC client. It contains all the goodies other clients on UNIX, Macintosh, and even on Windows offer, combined with a nice and clean user interface. It offers full color text lines, DCC File Send and Get capabilities, programmable aliases, a remote commands and events handler, place sensitive popup menus, a great Switchbar, World Wide Web and sound support, and a lot more.

It is shareware, but is not crippled in any way.

mIRC 6.34 has been released! (August 8th 2008)
This version of mIRC is a small though important update to the previous version and has been released primarily to resolve an important issue with ‘if’ statements being processed incorrectly in the scripting language.
Several other small issues have also been fixed in this release.

Although this is a minor update, it includes important changes and is a highly recommended download.
