Not only is it useful for you to see others on Nowbridge, it is useful for other members of your team to see you.  Nowbridge works best when all members of a team use it.  If one member is working remotely for the day, he or she will appreciate being able to see colleagues in the office.  Even those in the office but out of line of sight will find it useful.  Nowbridge can be set to automatically ask if you want it to start – see the settings window.
