My name is Elder Joshua Wood, and I'm currently serving in the Michigan Lansing Mission. A few months ago, our mission president informed us that in addition to serving as full-time missionaries in our proselyting areas, a few missionaries would become part of a pilot program for missionaries, using Facebook and other internet services as a proselyting tool. I was a little skeptical at first, admittedly, but I have since found the internet to be a very valuable contacting tool for missionary work.
