mongibello is not the "common name" used by the general public in everyday life to call the volcano etna, so it cannot be used in OSM under the tag "name" , meaning common name, because it is a falsity and decieving

the field "Common name" means the name normally known by the general public in everyday life. it cannot be used to publish announcements or recent event. for official bureaucratic names use the tag "official_name"

i did not write demanio forestale

the name in OSM is the "common name". common name means the name tupically used by the general public in everyday life. I have not written "Area Sommitale", so the "common name" of that area is "crateri sommitali"? for sure it is NOT "mongibello recente" .. i've never heard a single person saying "mongibello recente" when they refere to that area. so that is not the common name

these are minor corrections

if you know the place, make the changes yourself
