How do I create a class that happens every other week?

The owner creates a recurring class with the Every N weeks repeat.

1. In Schedule, tap Class, then Recurring class.
2. Under Repeat, choose Every N weeks, then Every "2 weeks" (2 to 8 weeks are possible) and check the Days.
3. Fill in Start, End, and choose Class starts.
4. Tap Save.

The rhythm is counted from the week of Class starts: the first week happens, the next does not, and so on. So pick as the start date a day in a week when the class happens.
