I am the communications person for a group of church missions leaders that meets every other month for lunch.  We have about 20 each time and 232 people are on the email distribution list.  I lead a prayer meeting for church missions leaders one hour every other month, in between our lunch meeting, sending the prayer sheet ahead of time. Few people were coming, so I changed the day of the week, but still few or no one came. So I changed it to a prayer phone call. I still only have one or no one join me. This is discouraging, especially because these are church leaders. If they do not see the value of praying with other church leaders, how can they lead their churches in prayer?  I may change the day of the week again.  I think this is so important and I do not give up easily, but if that doesn't work I may give up. Any ideas?
