Successful couple missionaries in Cape Town, send pictures of every group activity to local PH leaders. For example, missionaries train a ward council and then send pic of the ward council to the stake president. Or a SGB group starts, and they send a pic to the Bishops and stake president.
From Elder/Sister Johnson: "We take pictures of all the groups we have together including stake trainings, counsel trainings. Could be 100 people or a dozen people. Then we send those to the leaders to see what’s going on. All feel like they matter and leaders stay excited and engaged about what is happening."
