If آپ and a fellow writer are writing 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 کریں شائع it. Because we both do یا don't care who does, and are all like "oh, آپ can post it if آپ want" and "Oh no, why don't آپ 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!
