A quick update to the state of affairs with the Shodan Challenge for this year:
Firstly, the league website is not finished yet unfortunately. This will be finished as soon as is possible for people to begin playing and submitting games.
Secondly, there have not been many entries (around a dozen).
I've put in a few changes to the online league site to provide for the forthcoming Individual League.
People can update their status under "Update account" to indicate that they want to play in the Individual League. At the moment they'll just get plonked into the one and only division - we'll decide how the league is structured when we see how many people want to be included.
