Section 3a: Joining an existing work group / circle / project / micro-enterprise
When you find a working group / circle / project / micro-enterprise that you want to join, the first step is to review the information about that group.
In general all groups should communicate clearly whether they are open (anyone can join), open by invitation (only people invited into the group can join) or closed (not open for new members).
Each circle has autonomy as to how to manage their onboarding process, the membership criteria etc.
