Get rid of Shared Journals altogether
Short, concise description of the idea
Shared Journals are basically being used as communities now; we can get rid of the shared journal type ('S') and migrate over to a community format.
Full description of the idea
Shared journals are still being managed in an old-fashioned sort of way; they don't appear on the Community Management page, you still have to use the Admin Console to add/remove access, etc. There's nothing you can do with a shared journal that you can't do with a properly configured community (after a couple of adjustments are made). The reason why most people go for shared journals is that the userinfo page doesn't provide a link to join.
