I think that re-branding coins as ink is super cute, I guess it might be a little bit confusing to explain at first, but coins have always been kinda hard to explain.
saying "the ink you give me can be redeemed for actual money" seems a lot more clear than saying "tapas coins can be redeemed for actual money", mostly for semantic reasons I guess?
Also I love the idea of "inksgiving" I think previous coin drive campaigns really suffered from being somewhat of a surprise, having an annual event helps clear that up, and setting it up around thanksgiving really helps fuel that charitable spirit.
Gotta say, I'm looking forward to this change. (pun unintended?)
