Social media: guidelines and expertise for work-related use

I am re-posting information shared by Joseph Maddela on the CWP list on 5/13/16: 
 Are there campus guidelines/policies for creating a department social media account? Are there best practices for having a shared department account? Where can I find more information? 
 You can find the info at http://socialmedia.ucla.edu/
