I think Sunday deadlines are better than Friday for most people (chance to write on the weekend if the week is busy with obligations).

Also, I was wondering if there could be a requirement to comment on the gift(s) you receive (either just official fills or treats as well).

Although I've seen many people explain in the server that they haven't gotten around to commenting yet, I still know of multiple fics that don't have a comment from the person it was gifted too (and who have not said anything about it in the server). Idk just a thought.
