Private spaces are for specific projects.

The Groups section of the app is now called "Spaces" and dedicated to projects facilitating taking care of the community (Caremates and Leaders) or where specific rules apply (NSFWers). This is explained in the welcome post all new members are invited to read.

Caremates - a space for caremates.

Leaders - a space for sub-communities leaders.

NSWFers - a space for skin pics.
