I do not believe that the software Sparky has in place is going to let us change much in the way of our *account information*.
It is ridiculous to see how many people who try to register without following the directions of using their real first and last name in their account. Several a day, usually!
To get people to add their location might be as easy as trying to sandpaper a Bengal Tiger's butt.........
The signature is a great place to add such information as well as anything else. you care to share. AND, it can be easily changed at any time.
