I looked around for awhile and came to a very tentative conclusion that boundaries are for creating named sets of permissions for Bonfire posting and assigning those named permission sets to Bonfire users.Roughtly correct? Off by __?

Wait wait I think I got that wrong. You assign the named boundaries to a post, like this one, and that says what people can do with that post?Or am I still missing the point. Will got back to studying the docs....I think I continue to confuse boundaries and circles....

In that case, I'll study the ongoing explanations and discussions and try to summarize some rules for myself, which of course I will post here for comments and corrections.
