FAQ: Why isn't a particular group showing up on the GroupFinder?
There are a couple of things at play that will prevent a group from not showing up on the GroupFinder.
A. If the group is marked as a closed or full (max # of people reached), it won't show up.
B. The group could have the "Show on GroupFinder" turned off in it's GroupFinder Preferences.
C. The group is archived or inactive.
D. The group doesn't have a meeting location set, so it won't appear on the map view (but it will on the list view).
