<h2>How it works?</h2>
<ol>
<li>There can be random number of broadcasters.</li>
<li>All broadcasters will be interconnected!</li>
<li>All broadcasters can see/talk with each other!</li>
<li>There can be random number of anonymous viewers.</li>
<li>All viewers can watch/listen videos from all broadcasters!</li>
</ol>
<h2>Real-life scenarios?</h2>
<ol>
<li>5 CEOs can setup a presentation with many employees!</li>
<li>5 Teachers can teach many students in the same room!</li>
<li>Two ore more doctors can inspect two or more patients while LIVE teaching many students!</li>
</ol>
<h2>How to use it?</h2>
<ol>
<li>1st Tab: There MUST always be a room-moderator. Select "Room Moderator" and click "continue".</li>
<li>2nd Tab: Select "Anonymous Viewer" if you want to anonymously watch/listen all videos.</li>
<li>3rd Tab: Select "Broadcaster" if you want to setup two-way or multi-directional video chat with all other broadcasters.</li>
</ol>
