I recently came across a tip sheet from a writer named Craig Van Korlaar with simple suggestions for how congregations can effectively manage social media. I found it helpful, so I wanted to pass it along. You can find the guide at: http://topnonprofits.com/posting-guide/.
If you are looking for tools to help manage social media, the same website also offers a free editorial calendar that helps you plan what you are going to post. You can download that tool at: http://topnonprofits.com/free-editorial-calendar-campaign-planning-documents/.
