My coworker wrote a quick mvc chat application so we can chat about work stuff without leaving our desks.
What are some ways to indicate to each other a new message ha
You could play a tone or other audio clip when a new message displays.
The nice thing about an audible cue is that you are able to keep your eyes on your work until you come to a natural break point to answer the message. Visual cues, in my opinion, are more likely to interrupt your work flow.
Obviously you can make the audible cue as pleasant and non-intrusive as your imagination allows.
