Comment 1 for bug 837716

There is a proposed patch for this in the user/jeffdavis/trunk-lp837716-booking-notify branch of Sitka's Evergreen repo:

https://git.sitka.bclibraries.ca/gitweb/?p=sitka/evergreen.git;a=commit;h=refs/heads/user/jeffdavis/trunk-lp837716-booking-notify

This gives you a checkbox to enable email notification when creating the reservation, and adds a hook, reactor, and validator so that you can create an action trigger to send the emails. I've tested these changes against 2.0.8 and they seem to work.

One downside is that this would require a change to the booking.reservation table, namely adding an email_notify field. I couldn't see any other way of doing it.
