Hi @Mike Rizzo8
"Most Active Users" are calculated based on activity conducted within the community. You can see a breakdown of how the scoring is allocated by going to the Reputation App under Admin Panel > App Settings > Reputation App. You can also customize the scoring based on the type of activity you'd like to have within the community.
I've included more information regarding the Reputation App here4.
Where am I?
