The Doctor's Voicemail: Whenever you'd like to leave an IC question/message.
"Hello, hello. Uh, this is the Doctor speaking. Well, one of them. Anyhow, I'm not here, not at the moment, at any rate. Please do feel free to leave me a message. Oh, right, nearly forgot. Remember to leave your name and what year you're calling from so I have a general idea where and when to get ahold of you.
