Is it possible to submit a request of what manga we want to read?
only to scanlation groups, mangago doesn't translate stuff, it's only hosting site
go to scanlation group's site like their tumblr or such and message them. it's easy to know the translators, just check the scanlate credit page of your favourite manga and you'd see the link.
