Build a community website
Websites aren't just pages of content. They should include member-based access and functionality for sharing messages and articles, behind a privacy wall for member-to-member communications.
If you're a sports club or social society, you need a place for your visitors that isn't open like Facebook, but allows members to sign up for events, to register for teams, to make suggestions and organise happenings.
Perhaps you need a club shop, or want to manage membership subscriptions. And you need different levels of permissions for your club officers compared to regular members. All while providing a front-page to the public to encourge newcomers and new joiners.
