I need a better word that Blog for Haven (feel free to make suggestions!) because 'Blog' comes with all the connotations of public posting--but everything on Haven is private. So it's worse than creating an account, you need to have the owner of that Have create an account for you; there is no self-signup.

Account management is admittedly one of the weak parts of Haven's UX right now, but everything needs to be source-initiated or else spam is an even bigger issue. (That was my previous experience trying to do this on Wordpress). I've got ambitions of adopting IndieAuth and building Haven as an IndieAuth identity (IndieAuth is like Oauth, but you sign is as your domain instead of a user @ google/facebook/github/whatever). This would let account creation be more of a whitelisting process--just paste the names of the people (people identified as domains) to which you want to grant access, and authentication is handled by their own domains.
