In this post, I show how you can improve your standard Moodle 1.9.x chat module with Ajax Replacement Chat (ARC, May 2010). If you surfed to this post looking for a chatroom for your Moodle course, you will feel like a kid in a candy store. Sorry to keep you in suspense, but I will reveal more about ARC in a moment. First, a brief review of some more-commonly known chat methods or modules currently available for Moodle. At least one is a commercial offering, whilst the others are free.

Some tutors feel that the standard Moodle 1.9 chat is too slow and that it is a bit of a resource hog. I seldom use it because I find it slow and sluggish. In additon, it opens up as a separate window. I prefer if the chat interface were embedded within a Moodle course page itself.
