Just in case you are not familiar with group screen sharing, Microsoft has a handy video that shows how it works. Basically, it allows users to share images on their desktop with two or more people in a group Skype call. Allowing this feature to be free from now on will certainly be a huge help for people who use Skype a lot for group calls.
What do you think of Microsoft allowing group screen sharing to be access for free for Windows and Mac users?
