[As @ondrej also mentioned] I encourage you to create tutorials that will help the community members get to know all the different features of discourse. Either link them here to search for tutorials or create some yourself. Here is what I did for a community based on discourse:
→ Tips and Tricks for the Infinite Flight Community
→ How to use the community tools
→ How to read your profile
Let me know if you would like help in order to re-create them.
