Title: Duplicate Registration Last modified: September 1, 2016 --- # Duplicate Registration * [alcresearch](https://wordpress.org/support/users/alcresearch/) * (@alcresearch) * [9 years, 10 months ago](https://wordpress.org/support/topic/duplicate-registration-1/) * This is a great program, first off, but I am having one small issue. We use the program to have people register to participate in paid market research studies. Since it is very popular some people try to register twice. We check for duplicate registrations by email submitted. The issue is that if it is a duplicate they get a 404 error when they submit the form. Is there a way to either automatically send them the private link so they can update their information or have it redirect to a different page reminding them they have already registered. You can see the page at opinionseekers.com/join if it helps.

Do you have a custom redirect script available or do we need to hire someone? I would like a script that would display a page saying that an email has been sent to the email address on record and then send an email with the private link to edit the record if they want to just like the resend link does. Also, I would like to make a donation to you for the program, what would you suggest?

On that page, put the [pdb_signup_thanks] shortcode. that shortcode will close out the submission and send the email. It will also print the “thanks message” that is set up in the plugin settings. You can put any other content you want on that page of course. * It was sending them to the record edit page after signing up that would require a custom script. If you just want to say “thanks” and send them an email, that’s the normal setup.
