Which tutorial should I watch to setup autoresponder upon new user registration in DNN?

thanks in advance

If you want to alter the text of the emails go to:

admin menu / languages
language editor

press ctrl + F and type register

here you will see a list of the emails that DNN sends such as :
EMAIL_USER_REGISTRATION_PRIVATE_BODY.Text

If emails are not sending check out:

thanks,

Hello, I am getting about 1000 new registrants a day. Which means that I am getting flooded with "New User Registration" notification emails. How can I set DNN to NOT to send me New User emails. It's nice to know about them, but I can easily look them up in the admin panel. Just not wanting the added emails.

Thank you in advance.

This is a really simple question which you would expect a tick box to turn it off, but there isn't one.

All I can suggest is that you change the email address for your administrator account so that the emails do not go to your personal email. - This will also change the email address that sends the emails from your website.

Your other option would be to use DataSprings Dynamic Registration to replace the core registration and you should be able to change the notifications using that method. I would double check with DataSprings.com that this is the case.
