When a TimeToSignUp column is "closed," participants see the column and the items in the column, but they can not sign up for items in that column.
To allow people to sign up, the column needs to be opened.
- Log in
- Go to the sign up sheet
- Click on "Edit/delete column" at the top of the column
- Click on the "Show Advanced Options" button
- Change "Column is available for sign ups?" from "no" to "yes"
- Click on "Save Changes"
This will need to be repeated for each of the columns.
