Social Media Policy for Church?

I'm a member of Meadowlands CRC in Ancaster, ON, and we're at the point of needing to develop a policy for social media. 

Does your church have a social media policy that you're willing to share? What do people allow to be posted on their church Facebook pages? Who watches it? Who does the posting? 

Thanks for your help. It is much appreciated!
