Social media is just ways to get found. From my past experience it’s all about chapter dynamics. Surprisingly enough if the chapter is active the word gets out but social media helps. Be diverse in your activities, don’t get a reputation for being monolithic. People come to the chapter with different expectations. If they don’t see that expectation met you’ve probably lost that person forever.

One thing i don’t see on the list is the Chapter Blast that Chapter Office can put out for your chapter.
