I'm creating this bug after a suggestion was made on ptwiki's anti-vandalism project[1]: there could be a message[2] showing the amount of time (seconds?) which the user will have to wait until the edit is allowed. This kind of feature is used e.g. on download sites, when the user is not registered.
