How to send reminders for every class

When people sign up once for something that meets several times, like a six-week class or a camp week that runs Monday to Friday, the form keeps every class date. Each class gets its own reminder, the add-to-calendar button adds all of them, and the form's date line reads like "6 Tuesdays, November 3 to December 8".

Steps

1. Describe it with its dates, for example "6 Tuesdays from November 3, 6 to 8pm, $240 for the series". Reminders are on by default for a form with dates: an email the day before each class. Ask for a different time if you like, for example "the day before at 9am".
2. The builder lists the class dates it used in its reply. Check them, and say if one is wrong (a skipped holiday week, say).
3. Already built a series that shows only the first date? Ask in chat: "this meets every Tuesday for 6 weeks, add all the dates".

People still pay once for the whole series. If you would rather let them pick single weeks, ask for that and each week becomes its own option with its own price.
