When you register with the National Cipher Challenge, our system will send you an email containing a link to confirm your email address. Once you click on that link it will then send you a password for the site. Every year we get lots of emails bounced back because the email address is incorrect. For example a typical error message might look like
Welcome to the new web site of the University of Southampton National Cipher Challenge. The official 2010 Challenge will start at 3.15 on October 7th, and you can register online from September 14th. If you have an account from last year you can carry on using it, but we have deleted the info about who is on which team as we suspect some, maybe most, of the teams will change. As before if you want to enter on your own you only need an account, and if you want to invite someone to join in with you you can do so by using the Team Builder tab in your user profile. Good luck!
