I too had never noticed the registry option on your page. Is it a relatively new feature? I think it`s a good idea. Only thing that might be an improvement is adding a feature that emails you if an item from your registry (or wish list) goes on sale.
Just created my registry. I had just made one at AG cause my daughter likes to get me gift certs from there every year. This year I gave her some choices to buy me things that I want instead.
