The emails you see are sent by WordPress. Admins get emails when a new user is registered. It's correct and it's the default WordPress behaviour. You can disable the emails which are send to admins when a new user is registered using this video: https://www.youtube.com/watch?v=5LD9Loa0nCY

wpForo has it's own option which tries to disable this email as well. But you should try both. The wpForo option is located in wpForo > Settings > Email Settings. The option name is " New User Registration Email for Administrators".

Disable wpForo and use the WordPress native registration form to test. The native registration form can be found with this URL. Make sure you're logged out, this URL is only available for guests:

yourdomain.com/wp-login.php?action=register

As an alternative solution you can disable the registration with email confirmation and make it one step: https://wpforo.com/docs/wpforo-v2/settings/login-registration/#enable-user-registration-email-confirmation

This is not an issue of wpForo. Also an smtp plugin can't "mess" (as you say) anything. I would suggest to spend sometime to get familiar with Wordpress script.

I have the wpForo plugin working ok without sending a confirmation email out for new users when they register and now my contact page works properly.

When I do activate the confirmation email setting, instead of sending the email to the new user, it is sending it to my email instead.  This I need to fix up.  Any suggestions.

1. Contact to the hosting and ask them fix the email sending issue, this is probably disabled in PHP configuration.

2. Or just configure SMTP for your WordPress. Here are great plugins: https://wordpress.org/plugins/search/smtp/

Enable email logs with SMTP plugin and see the problems better: https://wpforms.com/how-to-set-up-wordpress-email-logs/

It should read "Dashboard > wpForo > Tools > Debug > Errors & issues"

So now that I see the error,  it says:

"WordPress Email sending function wp_mail() doesn't work!"

I am looking at the suggested article: https://www.wpbeginner.com/wp-tutorials/how-to-fix-wordpress-not-sending-email-issue/

But I am lost.  HELP!

You know I purchased this site and it gave me 5 Office 365 email addresses.  How the hell do I use one of them?

"Make sure your server email sender works well. Make sure you receive emails from your WordPress (on registration or on other cases...). You can check it in Dashboard > Forums > Tools > Debug > Errors & issues admin page. If the mail function doesn't work you'll see an error notification."

When I try to go to Dashboard > Forums  There is NO TOOLS MENU ITEM!

It just says "All Forums" and "Add New"

So debug this using an smtp (out email) plugin, with logging.
