Hi there,
I haven't been able to fully test the groups functionality yet but it looks like it doesn't include a leaderboard for groups. If leaderboards are also available within a group it would probably motivate group members to be more active within a group.
Points achieved with group interactions, should also be added to the user profile. Maybe even better to make it an option in the backend: Include group user points to total user points?
Great work sofar on the groups functionality by the way

Ewoud
