If you have a class that repeats every week, with the same teacher, at the same location, you can have Momence auto-schedule it for you going forward.
Recurring class settings allow you to choose:
how often the class recurs (ie. every 7 days)
how many classes to display in advance
to your staff (in case you need to sub someone out)
to your customers (in case they like to book in advance)
an end date to the series (if applicable)
