Users can set up a claim to the listing which they have not made. The admin can verify the claim request and then approve it. Then, the author of the listing will be changed.
After activating the addon, you may activate this function at Dashboard >> Items >> Claim tab.
Then you can add this function by using a shortcode.
Once the addon is activated, the menu named “Claims” emerges on the Dashboard, where you can check out the claim list which users compose.
