This feature allows a Performer to interact with users more efficiently. Performer can share their full desktop or some specific app on PC.
Here are some examples how to use it:
show how any program work in real time;
teach step by step how to draw via graphic design tool;
demonstrate photos to describe how perspective works;
and so on.
After successful demonstration you always can save this broadcasting as a MP4-video and put it in your Profile for sale.
