You can get CC involved in your community in a variety of different ways. The LiveContent project presents a bevy of opportunities in integrating CC in your area - from your local library to your local school district. Encouraging this usage is incredibly important for CC on a large-scale - integrating CC into local communities is one of the best ways to help spread CC's mission.
As always, evangelize amongst your peers, family, and friends to your best abilities! Informal person-to-person discussions are a great way to spread the word about CC - if you need talking points, check out our about page
