Did I set-up correctly the Pro Site?

Hi Support,

Can you please help me to check if I did the right set-up of the sites?
I just wanted to have a simple setup of the Pro Sites.
1. I wanted the user to easily register for the blog and then use the blog.
2. Upon registration they will receive an email or direct to a welcome page or message that they already register to the site and will receive an email for the credentials.
3. It is okay with me if the Admin needs first to verify the registration before the user can use the blog, but they need to see a message on the page upon registration.

Appreciate anyone's help.

Thanks
