You can change your location at the top of the page, above Q&A...what platform are you running on - Chrome, IE, Firefox?
You can also update your profile but going to your name, click the drop down menu and select "my stuff". you should be able to do all that you want there.
You might have to log out and log back in. I don't know how your system works.
Good luck!
