We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed.

I am not sure I am able to fully understand what you wanted to achieved.
BUT my question also is, how then would the users be able to access your feedback form if the feedback button for it was disabled?
Perhaps what you were looking for instead is an auto pop-up Lightbox form?
Refer to this guide -How-to-Auto-popup-a-Lightbox-Form
Hope this help. Inform us if you need further assistance.
