KoroIRC

KoroIRC is a small and free Windows IRC client that is inspired from mIRC, X-Chat and HydraIRC.
The setup file is about ~600k, yet the program retains full functionality, so it can be said that the design goals have been respected. So it is both small and very useful.
Here are some key features of "KoroIRC":

ï¿­ Allows to save all connection info as identity files for quick and easy retrieval when needed.
