The manage Sign-ups admin screen allows you to view all your sign-up data for a sheet in one place and also add, edit and clear spots. This is available for both the Free and Pro versions of the plugin.
The Manage Sign-ups admin page for a sheet displays the sheet name, date and description along with a table of all sign-up data such as columns for the task name, the name of the user that signed up, email, phone, or any other fields configured for that sheet. Options also exist on each spot to either delete, edit, view additional information or add a new sign-up on an empty spot. Clicking the “info” icon on a filled spot will show some additional information such as when the sign-up was added, last updated and the username and link to the user if they were logged into their user account when they signed up.
If you click the add or edit icons on any spot you will get a form similar to what the user fills out on the frontend where you can enter or update any information including associating sign-ups to existing WordPress user accounts.
The Edit Sign-up form (similar to the Add form) allows you to add/change data for each of the sign-up fields related to a sign-up such as first/last name, email, phone, and the user account the sign-up is linked to.
