I came here from being pretty heavily involved in Reddit. The only thing keeping me there is r/heinlein, I want to keep it going.
You probably know most of us on the society’s board from back then. The Heinlein Forum has many of us, and I even have a little group for those of us who were afh friends back then. If you’re on facebook leave a comment on a post on the Heinlein Society’s page mentioning this and I’ll find you. (Most recent post is better)
