Registration Windows
Registration windows control when each account type is allowed to start registering for a session’s classes. Each account type can open at a fixed time, or run as a lottery where families register in a drawn order.
Configuring Windows
Section titled “Configuring Windows”- Open the session and click the Registration Windows tab
- For each account type, tick its checkbox to allow registration — unticked types show Cannot register
- Choose a mode:
- Open Window — set the date and time registration opens for that account type
- Lottery — set the Lottery start time and the Slot duration (min) (default 15)
- Click Save Windows

The Current Windows summary at the bottom lists each type as “Opens [date]”, “Lottery mode — starts [date], 15min slots” or “Open immediately (no date set)”.
How Lottery Mode Works
Section titled “How Lottery Mode Works”In lottery mode every eligible family gets a lottery number, and a family’s window opens at the lottery start time plus (number − 1) × slot duration — #1 at the start time, #2 one slot later, and so on. Members see Lottery #N — opens [date] at [time] on the session until their turn, and an email plus push notification (“Your registration window is open!”) goes out automatically when each window opens.
After saving a lottery window, click Manage Assignments to draw or import the numbers — see Lottery Assignments. Before the first save the tab reads “Save windows first, then manage lottery assignments.”
