This is in response to the what's the worst that could happen thing.
Not on Mangatoon, but another site we nearly had a big issue. We were going to keep the copyright, but they were going to have the write to make whatever they wanted from our work and not give us a dime. They had things listed like video games, tv shows, and anything that could come about from future technology.
So yeah, we would own the sort but THEY'D have all the merchandise rights... which still leaves one with no money. I'm good with Webtoons and Tapas for now.
