The latest version of i² is 1.08, and works on mIRC 7.61 and most likely any later version. Check back here for news before trying any newer versions of mIRC that may be released. See the menu above for links to download and learn more about i².

There is an install.txt and an i2.msi installer included in the zip. Just click and run the i2.msi file, but the instructions below still works.
Simply unzip this to your mIRC directory, and type /load -rs i2.mrc in your mIRC, and work from there. Full docs are included. Note: Make sure to unload your default mIRC popups, if you have any, as i² will not do this for you.
