If you choose receiver, watch (in fullscreen press f). If you choose sender press up, move your mouse and once you are done press down. if you want to be sender and it's not there reload and if still not there is someone already as sender
8/3 : now 1 send 11/7: now 1 send actually works! 11/7: added button 11/7: added wait for sender to be receiver 11/7: wait for sender to be receiver wouldn't work so i got rid of it 11/7: added better way to tell if you are on as sender
