I don’t mean to bump old news, but I am finding a lot of promise in SeatReg for an outdoor craft fair like the OP. Adding a simple input in the settings to replace “seat” or “place” with a custom term, and another input to replace “room” with a different custom term would be a very welcome addition. I may resort to modifying code unless I find a different solution for a non-profit organization. On a related note, it would be nice for the user-facing scroll and zoom capabilities on the registration page to be more intuitive between desktop and mobile browsers.
