Very new to plugin stuff and taking baby steps so forgive me if this is obvious.
I have a simple notification service set up to send an email to the author of an entry (front end submitted) when it is saved.
This simply sends the email to $entry->author
The entry that gets submitted also has a related entry field and I'd like to send the author of that entry an email as well, but I'm not sure how I'd get access to them? Any pointers?
