Volunteer Sign Up Sheets documentation – Stephen Sherrard Plugins
You want to pay close attention to these two settings in the general settings, copied from the documentation:
- Show Expired Tasks? — If you want to save signup info even after the dates have expired, check this box. This ONLY affects the signup lists on the ADMIN side. The public sign up sheets will never show tasks/signups that have expired.
- Automatically clear expired signups? — Enables the hourly CRON function that checks for and deletes expired signups from the database. If you want to save your signup data after a task date has passed be sure to uncheck this and then check the above option to be able to view the expired tasks/signups on the admin side. If later on you want to manually delete all your expired signups, use the button on the CRON Functions page. For example, it is useful to clear all signups so that you can alter the dates on a sheet and reuse it for the following school year.
