No, I'm not sure how to approach that. The most fair method is probably to randomly assign them to a month, but if people have very strong preferences, I suppose I can do try to get people the month they want. Not sure what to do if two (or more) people want the same month, though. I was planning to give the most frequently endorsed photo the cover, however.
