I work at a nonprofit and love to organizational structure of Trello and see it as a way to post information and resources to families instead of using a website, blog, or sending by frequent emails.
I don't plan to use it as a workspace so much as a resource board. My question is whether I can maintain this on the free account version? From doing a bit of reading, it seems that I may be able to invite families as guests to a particular board. From sharing that board, they can then access documents, videos, calendars, etc... without needing a pro version account. Does this seem feasible?
