I was under the impression group membership is voluntary - that you can't add someone to a group, but rather you can invite them.
I want to create a Facebook entity that:
- Is open to everyone - everyone can leave or join at will
- The only one that can make use X be in the group is an action by user X
- Will be accessible to users that aren't signed to Facebook
A group doesn't seem to follow rules 2 and 3. Should I use a Fan page ? Or ... what is the best Facebook entity to capture this?
