Tip of the day: free screen sharing with Skype!

When you are in a video call and you want to share a screen you get the following message: "You need Skype Premium to share screens", and … you can have a free 7 days trial or buy Skype Premium at once. But, the following phrase made me curious: “Sharing screens on a video call or a group call is available as part of Skype Premium”. Implicitly, this means that when you are in a normal one to one Skype to Skype voice call WITHOUT VIDEO you still have free screen sharing. I tried it, here is the result …
No more pop up screen inviting you to pay for Skype Premium, and while calling the other person you still can see HIS (or HER) video! But he or she can’t see you. Therefore, screen sharing is still free! But Skype doesn’t tell you this in the pop-up screen, of course, business is business!
I tested this with version for Windows.
