Transition of our Communication central (gitter to matrix, ... a Solid chat)

for reference I list two different element/matrix links that can be used next week:

  1. https://app.element.io/#/room/#solid:matrix.org
  2. You're invited to talk on Matrix

Appendix: temporary I have created https://example.solidweb.org/public/chat/index.ttl#this
