During form development, I somehow created an account in AdobeFormsCentral with the intent of that ID (email address) being used as a form collaberator (The Account ID is my alternate Adobe email address on the main account. While the account was created, it was treated as a new user. That is not what I intended and I would like to know how to delete that account.
If you're looking to have that second Adobe ID you created completely erased, you'll want to email your request to our Privacy team. They can explain the risks of doing so.
If you'd like those two accounts merged under a single Adobe ID, our customer service department can help with that: http://helpx.adobe.com/contact.html
Please let me know if there's anything else we can help with!
