i want to put a Pad at the club for members to sign up as a volunteer for an event. Is there any kiosk mode? how to activate it?
You can enable kiosk mode via checkbox on the Details tab of your Event.
Here is more info on the kiosk feature from our Administration Guide:
Kiosk Mode is a special mode for the signup sheet which allows participants to sign up without having to confirm by email. It is intended as a way to easily signup volunteers at a meeting or some other gathering. When you check that you want the Kiosk Option and provide the kiosk password, this will add an extra link in the upper right corner of the Volunteer Signup Sheet titled Start Kiosk. When someone you have designated clicks on this link, they are prompted for the password you created. Successfully entering this password will put the Volunteer Signup Sheet into Kiosk Mode. In Kiosk mode when a volunteer signs up, they are immediately confirmed.
