You can close registrations for your challenge at any time. Doing so will mean that no-one else can register for your challenge. This may be useful if you have a fixed budget and you don't want to go over this for your additional participant costs.

Here's how to close registrations:

Open Your Admin Area

Log in to your admin area (your challenge URL with "/admin" at the end).

Go to the Settings Section

Click on "Settings"

Click on "User Authentication"

Change the Registration Status to "Closed Registration"
​Then click "Save Settings"

Registration for your challenge is now closed. You can change this back to "Open Registration" at any time.
