As shown in the image below, I have left a review on the comment submission form. I want members or guests registered by IP address to only leave a review once when commenting. When they comment again, the review on the form will disappear.
We're really sorry, but the wpDiscuz doesn't have such a feature.
Currently, we have paid plugin customization and custom addon development services at the gVectors Team. They can assess the work and create it for you. Just contact us via sales[at]gvectors.com email address and send a list of requirements you'd like to have.
In case you want to say thank you! 🙂 We'd really appreciate if you leave a good review on the plugin page. This is the best way to say thank you to this project and the support team.
