FAQ: What does a circle with a number in the middle on the GroupFinder mean?
If you see a circle with a number inside, that means there are multiple groups that meet at that single location. It's not possible to put to pins on the map in the same location with both being easily visible and click-able. Our solution is to convert it into a circle that has the number of groups that meet at the location and upon clicking on it, it will list the groups that meet there.
