Well this could be a problem for translators because for example in german there is no equivalent for "alerts" that makes sense in a forum software. I have used "Benachrichtigungen" for alerts and for notifications, which means the overlay will basically ask you

The solution is here to use a dedicated phrase for "Alerts" in this overlay which I doubt has been used. Please correct me if I'm wrong.
