At this time, each event in a recurring series is considered to be an individual event; there is no option to register for all events in a series. If members need to sign up for multiple events in a series, you could implement any of the following options:

• Create specific messaging in registration instructions and/or confirmation messaging to direct them to register for each event in the series. You could include links to each event, and/or provide a promo code discount to "zero out" the cost of any additional events in the series.
• If registration requires a payment, set the first event in the series up with a paid registration type, and have the remainder of each event set up with Staff Only registration types. Staff would then be responsible for registering each attendee for the following events via the back office.
