I am frankly disappointed, you found Challenge 7 far too easy! Anyway maybe Challenge 8 will make up for it!
Congratulations to all of you, I am amazed at how many are still in the running for the top prizes and I wish you all luck in this year's final challenge. I hope you enjoy it. There will be news about the Prizegiving published soon - we have great speakers lined up and I look forward to meeting some of you there.
