Use Themes to create visually stunning experiences for your visitors with clicks, not code. Start from a library of prebuilt themes in the Lightning Community Builder, and use them to create new communities, or update existing ones. 
 
It’s never been easier for community managers to engage and care for their members. Rather than posting individual messages to each of their members, community managers can craft a message once and post broadly. With one click in the engagement queue, the message is posted for a personalized interaction.
 
Make sure the most important content in your community gets maximum exposure with pinned posts. Pin up to three posts to the top of each topic or group feed and unpin them when you are finished.
