[opensuse-conference] communication to our conference goers

Heya team, I just wanted to let you all know: if you want to communicate something to the people going to the event, I can access the list of registered visitors and mail them collectively. So let me know if there is something you have to get out to them! Note that the conference-participant list is NOT the right way to talk to all conference goers as that list is opt-in so not everyone is on it! /Jos
