In last’s week class we were tasked with downloading and using an IRC client (I’m using Chatzilla for Firefox). The class populated the #teachingopensource channel, and our follow-on task was to use this space to talk back and forth in order to create a wiki page on the teaching open source website for a fellow student.
Using IRC is fairly straightforward. And while there are a number of advanced options, these are unneccesary to use the client.
