Sigmal

Sigmal is a fairly simple chat client for SigmaChat chats. Among its features are tabbed PMing, color support, and auto-rejoin after kicking.

Source Code

(Ignore this part if you're on Windows.)

Currently, there isn't even a way to make install. However, source can be obtained from Files for both Sigmal and the "sigmalhosts" hosts file editor. (The latter is a very simple program, and soon will be incorporated directly into Sigmal.)
