>I have not been able to find this. When you start entering an address in the To box in Gmail, it will display a dropdown list of possible addresses. There are a bunch on there that I no longer use. How can I edit this list or at least delete ones on it? Clearing cache/files does not work.

Jay, I think you need to open your contacts and look in there. I *think* that the dropdown references addresses in a certain subset of your contacts.
