Ok, I admit it. I am not current on current colloquial lingo and there something which just confuses me and no-one I speak to knows what it means. I have noticed that when some people write to me on Twitter, email or IM, they sometimes end a sentence with the letter “J”. Why? Is it supposed to be a reference to my name? Is it some sort of smiley or some “FTW” type thing? Please could someone explain this to me?
