Inviting new members and reviewing their answers to questions is essential to groups I'm building. The top link to invite seems to be for known, trusted folks. Using the bottom invitation gets them to the questions.
When I invited myself (under a different email), I answered the questions and got immediate access to the group. I need to vet folks through their questions before allowing them in. I had that before with Holochain Advocates. I used the basic URL of our group and folks used the questions, waited for my review, and then I accepted them through their profile. The current onboarding doesn't allow for me to review the answers to the questions. I have no idea where they even go.
