Thanks for the nice comments about the site, the feedback doesn’t sound critical it’s all helpful to know.
As an admin I made a test “private group” called Researchers and that’s the only group so far. I think people might be able to request to join it? We need someone other than me to be able to moderate groups and user levels. Hopefully Anna will be able to get her Admin access and we can then decide on how this works best and who can moderate and add new groups for testing this a bit better.
