Young Life is a Christian organization which aims to reach out to teenagers and young people across the US and the world to teach them religion and provide fun activities for them; the mission has been around for a long time now (since 1941, exactly), and is now exploring what the internet has to offer to attract more people to their ministry by presenting a nicely designed site with lots of videos and texts explaining what all the thing is about, and recruiting people for their a wide variety of summers camps and club meetings, a full catatlogue of which is available at the site. Note that the group does not belong to any specific Christian denomination, but rather aims to provide a supportive atmosphere for teenagers.
If you enjoy volunteering, make sure you stop by at this site to learn about becoming a camp leader to help young audiences, ranging from small children to young adults, and if you already are a supporter of the ministry, show you care by shopping the online store for apparel and merchandise.
