Linux users come in multiple levels: beginner, advanced and expert. But yes most, if not all, of them have advanced computer skills compared to Windows users. That doesn't mean we can do miracles. The newest banner makes it seem that, old browser and old flash or not, you won't be able to access your castle through anything but Plarium Play. Since they can't be bothered to make a Linux version of Plarium Play or let any of us do it, they should at least confirm that we can play with an old browser and old version of flash/pepperflash. And yes they should tell us if they are using an old kill switch free version of pepperflash or not.
