So far, I've tested :
- Asking people to help me pick leaderboards level names
- Asking to brainstorm on the name of a paid community (in the free one)
And people are loving it.
It's a very simple way to make them feel part of the process.
For example, in one of my community, they named level 6 "Queen simplicity". And now, every time someone reaches it, they congratulate each other saying they are now also a Queen simplicity.
Letting your community come up with the names they are going to name themselves inside the group is very powerful to create a feeling of belonging.
Let me know if you tried this!
