I have been asked to compile the responses to this query. Here is a summary:
-Contact incoming students at the beginning of the semester, when they are excited to get involved
-Like related pages (e.g. other departments in your institution, museums, libraries, individual artist pages)
-Keep current or they will lose interest. Aim for activity once a day, even if it's just to like other pages. Keep the content varied.
-Include the URLs of social media pages in email correspondence and make them visible wherever possible
-Create Twitter, Tumblr, and Pinterest accounts that have links to Facebook
-Create a Facebook link on the department website, and vice versa
-Create a YouTube video advertising the department's services and post it
on Facebook/Twitter
-Post opinion polls asking for feedback on social media content (and services)
Hopefully I'm not missing anything.
Thanks again!
