I have a link to my wedding registry at http://www.yishaandbarry.com/registries.php and it looks like the registries are not blocking the spiders. Check out http://www.google.com/search?q=http:...x?grid=9301240 - it is indexed.
So why is this an issue and why is my finance upset with me?
Well, people are buying things from our registry without knowing it. So they may order 10 items from our registry, but we never get them. People look at the registry, see we already have twenty spoons and they decide to get us something else. So my fiance has to go back into the registries and 0 out all the items we did not get. She is kinda at me.
Seems like 219 registries from Crate and Barrel are online, see here.
