A central part of finding the right people for your community is being clear about the cultural values that you hold dear. Sometimes you know where these are from the get go, and sometimes these cultural norms are emergent as the community grows together.
We found it helpful for example to go through certain questions about food, personal boundaries and so on, to find out who we all were.
This is our food survey for example This is our boundaries spreadsheet. Filling this in, we learn that some people don't like hugs, some people feel uncomfortable with semi nakedness in their private space and so on. We never would have known this without asking these questions explicitly. It's not that you all have to feel the same on all these axes, but it's good to know what is important to each other!
