I stepped through the introduction on Action Mailer Basics here:
Action Mailer Basics — Ruby on Rails Guides
up through 2.1.3,
In 2.1.4, I already had a user class, so I just copied the line
UserMailer.welcome_email(@user).deliver

app/controllers/users_controller.rb:285:in `mail_contact'
app/controllers/users_controller.rb:409:in `add_contact'
user_mailer.rb looks like this:
