I'm new to writing Apex triggers, and I'm not really sure where to start, so I'm hoping someone can help me. We currently have a trigger as part of our managed package that creates a new record for an Object called Related Address when you update the address field on a contact record.

I would basically like to copy this trigger for our email address field on the contact. Because it's part of our managed package, I can't view what the Trigger coding is to just mimick it myself. We already have the Related Email object created, so now I just need to figure out how to format the Trigger. Can anybody advise me on a trigger to do this? I would be much appreciated!
