Seeing what you’re seeing helps me to better understand your message, to learn from you, to help get things done. And with more work being done on a screen of some sort, the ability to share screens is increasingly important.
A variety of solutions have been available in the marketplace to provide this service, and they’ve continually enhanced their capabilities over the years. But there are also simple versions of screen sharing solutions, ones that are free.
I’ve used join.me many times, always with good results. It’s quick and easy to establish a connection, either as the host or as a participant. The features are basic, but most of the time that’s all you need to collaborate in small groups. And there are even mobile versions for Android, the iPhone and the iPad.
