generated MyMailer mailer and method welcome_email. Configured developement.rb file to use a new gmail address to send emails on behalf of OpinionNation team . In production we'd likely use a service like Sendgrid to take care of our emails.  The gmail's username and password are set to enviroment variables and will need to be set on each of your local machines (contact me for those details). Right now all test emails have been sent from the terminal until an interceptor is created to catch these emails and redirect them to us during developement. Once this intercepter is created we can begin to put mailer actions inside the rails controllers. Example, inside User#create: MyMailer.welcome_email(@user).deliver
intercepter in place. You'll need to set 3 local variables on your dev enviromenent. GMAIL_USERNAME, the email address that is sending the mail for the app, GMAIL_PASSWORD, the password for that account, and YOUR_GMAIL, which is your email address that all intercepted emails get sent to. Have fun.
Some swap files were deleted. Slightly cleaned up
switched order of execution in users#create in order to render page first upon save and then send email. I believe this speeds up the render
added a Answer method mentioned_users that looks at answer and returns any users that are mentioned in an answer via @ symbol such as @brant. Also there is a new MyMailer method called mention_email
