Here's a simple topic that's been on the brain some time. When referring to your friends or people you've met, do you like to address them by their user, character, or real name? Often times, people don't mind either or while some like to be called upon on a certain name to know you're talking to them (usually depending on their name, for example, two Whitefangs or the other person very familiar under a singular name).
I often take to referring people by their user or character name. I like to have the courtesy in doing so because, well, they like their alternative identity. Why not respect it? Even when I'm in a private chat with them, I still refer to their user. Occasionally I'll throw their real name to them, however, it would be either for serious conversation or to make a inside joke.
How about you all? What do you address people with? Their user, nickname, real name?
