As one who enjoys the roleplaying aspects of the game, I find no need whatsoever to divulge anything about the person behind the keyboard.
What does it matter who sits behind the keyboard? I don't care. All that matters are my reactions to and from those heroes and heroines my characters interact with.
I'm not looking for buddies nor am I looking for a love interest through this game, to me and many of those I play with, it is all about the roleplaying.
As far as OOC, I might tell you my age and certainly my part of the world I live in so that I can find others my own age and time zone to game with.
