Is there anyway to change your username? I realized being the idiot I am that I used a username easily identifiable by individuals close to me. I suddenly got nervous of people reading some posts about what I do. This is impractical for the most part but still it would put me at ease from a privacy standpoint if I could switch names.
Scroll down until the end of the page. There, you'll find the section "site functions" and, between those, you'll see the words "username change".
