Hi folks,
someone asked me (on the Drab Chat!) how hard would be to add the presence list to the Chat Example. I found quite helpful to build it, as it seems to be a good way to teach Drabs onconnect and ondisconnect callbacks.
Here it goes: Drab: Server Side User Interface Access
Again, please treat it only as a learning case. There are much better ways to track users presence in Phoenix
