(Sad I missed that discussion live for I had to sleep and stuff)
However, even though a PDF is good to create a static library of all tasty recipes DayKnights will provide, may I suggest a Pinterest board where all recipes could be put togheter and every late comers could still join the party because that kind of thing can always be updated! The google form is a good idea in the way that every submitters could send in the link to their recipe(s) they would have previously pinned and the board manager would literally just have to re-pin it (them)! You save time on the word transformation/pdf conversion and you keep every DayKnights included!
My 2 cents!
