Hello All, I'm looking for a way to grant access ("edit" permission) on an individual node to an individual user using the Rules module, and i.e. to only a subset of fields of that node. E.g. a user with an "evaluator" role can "evaluate" a project. The actions that come with that are programmed through Flags + Rules. The evaluating user should now get permission to edit certain fields of the project node. How would i do that? Any help greatly appreciated! Best, Toon
