Maybe I'm just paranoid, but I'm not super keen on having my email address out in the open. I'm guessing that is also why Yabur spelled out "at" instead of @, which you edited into the first post.
I can PM it to everyone in the game.
That's precisely why I did that. That e-mail's my main one, so I try to avoid it getting spammed whenever I can. Though Yahoo's spam blocker is good enough that if it does get printed like it has been above, I don't freak out.
