If 당신 and a fellow writer are 글쓰기 a collabfic together, who should be the one to post it?

Because I always have trouble when I write collabs with others on who should 게시하기 it. Because we both do 또는 don't care who does, and are all like "oh, 당신 can post it if 당신 want" and "Oh no, why don't 당신 post it?" because we would feel guilty if we were the ones to post it, but at the same time jealous if the partner did instead...so, help!
