conuly suggested making a vegan card for people, and I had thought of doing two different sizes (to make bingos easier) so I may end up with four community cards. The vegan ones would take care of the seafood issue, and I could also double check and eliminate any common allergens from those cards as well. And when I post the cards in the community, I will use your idea and let people know that they can swap out a square (or more) if needed. The goal is to make these as easy and fun as possible; I don't want to add to anyone's stress.
