Thank you for the information. For most of our sign-up sheets, we have another staff member copied to receive the status email in charge of that event/shifts. They do not access WP so would not be able to do an export. So they rely on the last status email received to see who the volunteers are scheduled for each shift. With the phone number they would have the most pertinent contact info if they need to reach the volunteer on the day of their shift. That is our main use, although if we had sheet specific custom fields, then I could also see a benefit for our staff as well to get specific response to a question related to that event/shift. This way the two of us who set the shifts up in WP do not really need to take additional action beyond setup.
