I've never really thought about calling people by their real names if I knew them. I call you Bill because honestly I couldn't tell you what your screenname is right now, but I guess I could call sam James, and ses Sarah, and FLY Richard or Rich and FroHam Corey. Wait, FroHam is an awesome name, I would never not use FroHam. Well anyway. I've seen people call sdedalus Sean. Plus I guess there are those that use their real names: Colleen, Keith, Matt, Carly and Edgar.
Okay, now I gotta make a table for my own amusement. Is that weird?
