Cool email tool

I haven’t played on Live in years, and whatever email address I originally used to register my gamertag with I’ve long forgotten. I want to get back into it – so, I’m either trying to find out what email address I used, or im trying to change the forgotten email address it to my current email address. Is there any way to do this? I’ve tried contacting Xbox Live support, and they’re no help.

I don’t understand how the stock market works.

And please answer, who would be the best president?
