I've been tasked with sending a notification email once a new item is added through a Module.

I used the Publish hook, before realizing that it will run the thing any time it's published, so each subsequent update, which we don't want.

I'm thinking I just need to check for existence of the record before, but that brings me to a question about how the records work: when you go to add a new item in a Module, does it create the record in that moment, then after filling out the form, it uses an Update action rather than Create? And even still, is there any hook I can use only for Create, and not for Update?

The inputs on the form where I manage Reports seem to be just a bit too wide. Not sure if there's a styles caching issue here or just some CSS in need of updating?
