There are scanlation groups that put their information on the first or last page of their project (webtoon/manhwa/manhua that they're currently scanlating). Most scanlation groups have discord so I believe it's best to look there but other platforms work as well. You could also create your own scanlation team and take up dropped comics or comics yet released/scanlated.
To upload a comic that is yet on this site, I believe you have to inform mangago / one of the administrators (?)
To upload chapters to a comic, click the comic and on the far left side, there is a white flag over a black box. Click the flag and on the bottom should say "Upload chapter". Your pages need to be on imgur or imgbox since google docs doesn't work anymore.
Thank you very much information
Hi guys, I'm curious how do you translate and upload manga here. I actually translate few webtoons which aren't that popular and I wanted to find a page where I would easily choose manga/manhwa and translate it, maybe something like Webtoon Translation. I would be very thankful (づ￣ ³￣)づ
