[mch2021-orga] Different jitsi channel and map instructions for virtual kickoff

[Elger / Stitch]

Hi all,

Riz00m has made a great MCH themed map for the virtual kickoff. We meet at the Main Stage, which is in the center of the map. When you spawn, walk down and you'll find it.

If you don't want to use workadventure, but want to join the meeting directly, you can. This link has changed a bit, which is now at:

See you this afternoon,
Stitch
