Recently has new co-worker introduce this for us cooperate together, and as I had tried out, yes! It’s been real cool, that you could just create the company or team name to share and communicate with other directly. It’s also like in skype you could see who is exactly on line(0n board) that you could communicate directly. so in this case, you will not miss the work free time(which you could see that he/she is on line), and also this include the app that you could download that your co-worker barely miss your alarm, the app will send the notification for the telephone.
It simply and easy use, very user instinct that everyone could use it right away!
