Does anyone can tell me

I think you have to contact the site itself

I'd like to know as well. I mean I know how to add new chapters to existing titles, which I do from time to time but I have no clue on how to add new titles. Anyone?

How did you add the new chapter to the existing titles???

Go to the title you want to add chapters to, on the extreme left corner you'll find a little flag icon, click it, check on the others option then add chapter number & link. That's it, Mangago will contact you via notifications.

Thank you
