There is no limit on the number of appointments a member can potentially book in each month.

However even though they may have unlimited appointments per month, these can only be pre-booked 2 in advance. (this number is selected within settings)

This rule prevents over-booking as members are forced to wait until they have attended one of these appointments, before booking the next.

Better still, many members have a date in the the month when they need to guarantee an appointment. They will then book this date, and only have 1 booking to play with.

This is just one of the BLOCS rules.
