WinChat
WinChat is a simple instant messaging app.

I started this project to get a grasp of the network programming I would need to know if I were to add multiplayer support to Nothin' Fancy. The application has few features, but everything is done at a low level, only using old Win32 APIs to get the job done. You can download the current version (1.0.0) here. The source can be found here.
