SALT LAKE CITY (RNS) Not so long ago, Mormon missionaries were prohibited from using the Internet, even to contact their families. The system then loosened a bit to allow weekly e-mails home and some occasional viewing of church materials. Now the nearly 14 million-member Church of Jesus Christ of Latter-day Saints is attempting to revolutionize the way Mormons find converts — and it's all online. The move involves experimenting with blogging missionaries, self-produced member profiles and stereotype-busting videos. The American-born church, which has been harnessing technology to promote the faith since the 1920 radio days, sees great potential in fast-paced storytelling.
