Some of the challenges may require supplementary data or some additional explanation. This is the temporary home for those artefacts during the conference CTF.
As things change, we'll update but the emphasis will be on function rather than form. Fancy HTML takes time but by all means report broken links since someone else may be struggling too.
The CTF support team are here to assist where possible, but in fairness to all competitors we can not provide answers.
That said, we can certainly check questions for clarity, look at your current answers and in some cases offer guidance.
