This is a plugin for Kerbal Space Program that adds Internet Relay Chat (IRC) to the game.
For more information, please visit the Forums Feedback Thread.
The mfd_irc.cfg is an optional patch that will add IRC chat to the MFDs in RasterPropMonitor. It will display whatever channel was currently selected in the KSP_IRC GUI, so you need to set that up first. Click the "crew" button on the MFD multiple times to access the page.
