Contact CampTix Attendees who Had Trouble Registering

[coreymckrill]

Moving this over from Meta Trac:

It's normal for CampTix installations to get a significant number of failed registrations (i.e., Attendee posts with the Failed or Timeout post status). Often times the user will try again later and successfully register, but sometimes they don't try, or they try several times and can't get it working at all, possibly because they're having trouble with the payment gateway.

It'd be useful for WordCamp organizers to be able to e-mail any attendees that failed registration, so that they can offer help. The existing Tools > Notify screen can be used to send the e-mail. The e-mail should not be sent to attendees who have previously received one, or who successfully registered on their own after their initial attempt failed.

The existing patch submitted on the Trac ticket two years ago is no longer mergable, so may need to be updated or even completely rewritten at this point.

Any news about this issue? We always have a lot of timeout tickets, and some try and register later, but some no, and they're people that would be really interested in the event, since they started a registration, we lack an easy way to contact them.
