Email Address Verification - Order Placement and Constant Contact

In an earlier thread I have posted a request for the exact code necessary and on what pages to require that the user verify his email address. (Just like the set up in the registration solution pack).

Ray indicates in that string, that this was removed from Power Store 4 release because it was "not necessary" for a user to do this. (I understand it was in Power Store 3, but I don't have this version to look at) It still shows "not verified" on the detail page of Power Store 4.

I would like to have this function for two reasons.

1. When the user actually places his order by logging in, the email address being shown on that page must be correct for follow-up and and confirmation of purchase, etc.

2. I have created a query to create a report pulled from the database that my client will use for sending out email blasts using Constant Contact. (exporting a CSV file with all the email addresses) and importing them into this program. For those who have used this program, you know that email addresses are verified and bogus addresses eliminated.

The info that Ray has posted is too general for me to accomplish this. I would appreciate you giving me the exact code necessary and where to place it on the profile page as well as the validation/registration email php pages or any others where required.

Thank you for your help on this.
