We have made one important change this year which is to move the competition points deadlines back to 11pm. We used to say up to midnight, but firstly that is a bit unfair on younger competitors, secondly it is a bit late for us to be helping if there is a problem, and thirdly it is much clearer what we mean. (Does midnight mean 00.00.00 or 24.00.00 – computers (and competitors) care about things like that!)
