So our site typically has minimal users, myself and a few admins. We login properly and make the edits to the site. 
We have a forum set-up coming online. Our registrants to the forum will get an email when they register. They’ll register from the bbpress shortcode I included on a page. 
Instead of saying “Welcome the forum”, the email they receive says New User Registration.
The URL it provides is the /wp-login, not the page with the bbpress login shortcode. It’s a default WP registration and login. 
I’d liked to customize emails going to forum registrants that are specific to the forum.
Does that make sense?

		OK-but most of those would affect all user registrations, right? I am trying to edit only forum registrant emails. 
Thx–
