I second Josh's comments.
Also, maybe since we can't really view each other's expressions when we're posting, we can use some symbols. How about:
;) Means - "I was just kidding; I really don't think your mother is the Incubus. Lighten up, my friend."
;P Means - "You are wrong! I stick out my tongue and spit at you!"
;( Means - "That is an incorrect assessment! I wish you a pox and a murrain on your cattle!"
7:) Means - "Ronald Reagan is smiling!"
I hope this clears things up.
