Before I congratulate you on being Poster of the Year KB I demand a recount. It's all too easy for the counter of posts to claim to be Poster of the Year. In fact I have just had a bit of a count myself and it would seem that I am, in fact, Poster of the Year 2006. Who are the mathematicians on this thread? Remember this is Poster of the Year 2006 and therefore only posts up to 30 December can be included. This is becoming a saga and it's not over yet.
