I remember reading a fan fic where Lois and Clark were pen pals before they actually met, but I can't remember what it was called. The situation was they didn't know each others names. I was partly reminded of this because in the recently published young adult novel about Lois, ''Fallout", she has a secure instant messenger correspondence with a person who goes by SmallvilleGuy, who I am sure is Clark even though Lois does not yet know this.
