How do I upload a new manga here?

Your best way to know would probably be contacting some translation or uploader team here itself.

But from what I've heard, you've first got to contact the mgg through their email to make a page for the manga and then only can you upload. Idk anything else tho since I'm not an uploader.

i think u have to contact the mangago admins through email and request them to add the story, and then you can upload the chapters

I could dm you how, I uploaded a manhwa here already

Please do. Thank you sm
