I need help to display website visitor's name (on the popups) by just url?
For example this wordpress website:
https://ngantenstory.id/agus-henny/?u=Jonathan
You can change the name to anything and it will display the exact name on the welcome popups.
No need user database, I assume? No need for the user to register first, etc.
How to do this? Please help.
Thank you.
