In the Partner Centre, click on Session Dates. This tab allows you to Pause your group and restart it at a later date. To do this, click on Reschedule for the week you want to change and click in the box to the left of Reschedule. A drop-down calendar will appear where you can choose the date for the next session. Once you have chosen the new date, click Update. All sessions after this date will now be updated to one week later.
