Hi, I would like to request a username change for the simple reason that I registered this account when I was 13 or so (and just thought it sounded cool) and I go by a different username on other platforms so I want them to be consistent.
Male is the default unless you change it, so that would explain how it happened.
Click "User Tools" at the top of the page.
That will produce a menu containing "User Control Panel" Click that.
Now click Edit Profile, and scroll down until you see a dropdown box under the heading Gender.(In the Biography section)
I assume you can figure out what to do from there... (Just remember to scroll to the bottom of the page and Save Changes once you have adjusted your gender.)
