Will my nickname show up on Yahoo answers or my real name?

I got my E-mail first, so that I could go on facebook. Now I decided that I wanted to actively use my e-mail account. Theres this thing about a display name or your real name. My display name is super slug. So Im pretty much just wondering if "superslug" is whats going to show up when I make a public announcement like I am now. Also will my friends on E-mail see Superslug or my real name?
