SUC - a Slack Clone for Modern Unix

I love simple CLI tools and am a big fan of the Unix philosophy. Recently I came across The Dam, a public Unix server that implements a clever tool they termed suc - the Simple Unix Chat. Essentially, it applies the Unix philophy to create a simple chat tool that can be used on any modern Unix server. The key code consists of just a few lines of Bash code. Check out the documentation for it here.
