Deploy a system to offer invitation-based text chat support to users

We deployed a system to offer invitation-based text chat support to users. This system allow us to move support requests from asynchronous email to synchronous text chat whenever this promises quicker resolution of issues. Sherief implemented this system, Lunar reviewed it, and Colin deployed it. The system is available as of May 29, 2014. A screenshot of a sample session is available. That concludes this task.
