How Does one change the email for the site.?

I have another email address. How do I change it here. I have been trying to find where I can make changes on the site for the emails to go to my new email address.
I maybe just blind to this. Can someone point me the right direction here so I can change it. My old email does not always work that well.

Go to the top tool bar on the site .... you can change it there .................. where it says profile..........

Thanks I change it now, Hope it works.
