Google Apps Scripts

I use Google Forms for event registration, and the notification email from Google is nice, but I want to be able to send an email to people after they’ve registered, possibly including information which is not on the generally available form.

So I need some extra functionality, and like to catalog my adapted scripts for re-use and sharing.

For example:

1. Sending an email upon each registration with additional event details (and as confirmation).
2. Checking if the maximum number of responses has been received, and, if so, closing the form (also opening and closing on particular date/time).
