no @GromNaN you don't pluralize the users part. Keep it singular. I think that is why @weaverryan thinks that is less correct. because it will be prone to more subtleties. Our brain usually is accustomed to certain things over time, use cases of the language. So far i had seen and used always the she, disregarding if it is male gendered. So for me this is new. I can adapt of course. Language just follows trends and is fine so as long as it is clear.
