When you edit your account settings in Google Analytics you can do a number of things:
1) Check your Google Analytics UA (Urchin Account) number.
2) Change your Google Analytics account name. It is best to give it a meaningful name and prefix a number to the name in order to raise it to the top of your list (if you have many accounts).
3) Agree to share your Google Analytics data with other Google Products like Google Adwords Conversion Optimizer that relies on reading your conversion data.
4) Agree to share your Google Analytics data anonymously with Google and others via the Google Analytics benchmarking service.
