The absolute only thing that should not be available to anon accounts is modded lenses and multitopics. Everything else including preferences (no matter how redundant) should be allowed to be used by anon whatever

You're gonna need to be logged into an account to save and retrieve stuff (unless we store preferences in local storage which is something else I'm considering)

But my plan is to separate authentication of contributions from being logged in; so you can be logged in for saved preferences and such and still post anon.
