So, in this edition of Speed Briefs we give you a quiz and lists.

About the quiz. Firstly, what can you win? A tree. Also winnable is booze and other food stuffs. Entering isn’t overly taxing: follow @speedcomms on Twitter and at midday each day in the run-up to Christmas we will tweet a question. The answer to the day’s question and the winner will also be announced via @speedcomms
