I've noticed that there's a difference between the number of participants in a space as reported by the People view (e.g./clearspace/people?view=status&cid=4552) and the User Adoption report. E.g. I have a space that lists 72 participants, but the report shows 152 active, 28 participating, and 21 contributing. Can you explain the differences? We're on Jive 4.5.x.
