The ACA just launched a redesigned website. The main domain name hasn’t changed but the files are in new directories and many have been renamed, so you cipher fans may encounter broken links. Please update your own if you have any on your puzzle caches, etc. Here’s the URL for the new Cipher Types page: http://www.cryptogram.org/resources/cipher-types/
Speaking of the ACA, I will be attending the convention in Irving, Texas next weekend and presenting a talk on a method for solving Foursquare ciphers. I hope to see some of my long-time ACA friends and make some new ones.
