I just signed up for our wedding registry. Nothing there yet. I'm still trying to figure this out :)
This is the website: www.myregistry.com
It's not your typical registry and may be a little confusing. If you click on a gift the website will redirect to you to the store the gift can be purchased at and then you need indicate in the myregistry website that the gift was purchased. I dont think it automatically does it for you.... I chose it because I can choose gifts from any store and not limited to just one store. It's pretty cool. The demo really helps in case you get stuck.
