Each registry has its own address. Hosts copy the link or share it by email from the dashboard. The page shows the event, the days to go, the message, how many gifts are bought, and where gifts can ship. Items still needed come first; fully bought items move to Already bought so nobody buys twice.
The page uses your theme. You can also copy the template to
yourtheme/wolfiz-gift-registry/registry.php and change it.
