FI and I have careers where our reputations and biographies are of great interest to our current and potential employers. So we're very aware of any information posted about us on the internet.
Just FYI, unless you make an effort to get your registry information off the internet, it is posted in full public view to anyone who Googles your name, not just your guests when they go to the store's website. When we googled our names, we found both of our full names, the city and state where we live, and our registries up for anyone to see. We only have experience with Crate and Barrel, BBB, and Macy's, but they all automatically send your registry to 3rd-party sites like WeddingChannel and Amazing Registry, which then post your information on the web.
Of course, I want our guests to be able to find our registries on the stores' sites, but I don't want just anyone who googles my name to see it. I am very protective of my professional reputation and I don't want personal stuff up there.
We removed our registry from Macy's entirely because there is NO option to take our registry off 3rd-party sites. At Crate and Barrel, you can change the setting online, but you have to dig a little. With BBB, I had to call customer service and they had to take it off themselves.
So if you care about your personal info on the web, you might want to check it out!
