In addition to the great suggestions by by others above, I have 3 requests:
1) Send an admin email including the volunteer's field data... There is a distinct possibility that not everyone who needs access to this information will either have WP admin access OR if there are last minute changes - then at the very least the email will arrive to those who need to know. This doesn't need to be anything fancy - just an email sent to the admin email in the settings saying:
name, email, phone # (address for those who use that) signed up for OR cancelled - Signup Date, & Slot (status of the number of current open slots would be a cool thing). I sent you an email from your website about a week ago with this request - I own the Pro version.
2) Allow a customization of text in the notification email to the volunteer My clent wanted me to tweak the email sent to the individual who signs up - changing the language just a bit in the cancel option an , and I was able to do this in the mail.php file to change the cancellation language and remove the email link in their case, but obviously with an update that will be overwritten... If there would be a way to either pop changes to the email templates into a "child theme" or options for this in the set-up menu, that would make this pretty perfect
3) Include the ability to add "time" - start / end to each signup already tied to date - this would enable setting up shifts.
Thank you so much! Great plugin.
