a lotta ppl submitted for their contest, but they take in entries year long.
from what I know, they look for webtoons but they'll look at anything you send them. this past month they started publishing manga from Hakusensha.
the whole payment thing is still fresh in everyone's minds, but it looks like they've settled with all the creators. the big news in Korea was that the revamping of their publishing contracts due to creator demands.
you could send them something and then tell us all about it after~
