1) delete as in totally gone from DB without a trace it ever existed?
3) Role based access control control list... can be used to control anything and everything on yourself... you the developer decides! Basically i envision it as some kind of "framework" to determine "permission/access" of each user... then the developer decides what each permission allows/doesn't allow the user to do. Details non cuz i haven't really decided how to do it yet! lol
