I found firstly
This thread where I am posting a score, then for some reason I say to cate "Bit slow there" and then I go on a rant about not being able to post scores.... It's actually quite hilarious some of the banter going back and forth
And got to love page 2 of this page. Dana's comment is quality below the final results bit.
LinkyIn fact that whole thread is class! I'm so keen to contribute ideas

Still don't know exactly where the rule came from though....?
