What If All Church “Programs” that Compelled Service Were Abolished?

I live in a very transient ward. Some month we get up to 30 new members moving in and roughly the same amount moving out; most of these we never see in church. It's the nature of our ward and it has its pros and cons. This results in the fact that we have a significant number of members on our rolls that we don't know. They are just a name with few facts. About a year ago I went through the ward roster and marked each name that I didn't know. With roughly 500 members on the roles, 190 names were unfamiliar to me. This was concerning. I stewed over this problem for weeks and knew I needed to find a solution. Reactivating these 190 names was a long shot; however, I felt it was our duty to at least know who these people were and understand their basic life situation even if they didn't want to attend church with us.
