@heluecht et al. Please note that the old guppe groups on the main domain do not exist anymore.
It is now https://a.gup.pe where you find a few documentation.
Also I would like to add that this is a relay-group with public only addressing.
It is mega nice that it is specified.
In the meeting we had identified more questions and different implementations like e.g.
for the governance of the membership list or the things like context, covered in the meeting attached text by @cpmoser etc.
