American Cryptogram Association (ACA) is a non-profit organization
dedicated to promoting the hobby and art of cryptanalysis -- that is,
learning to break ciphers.
Now is an ideal time to join the ACA. While supplies last, new members will receive a CD-ROM containing the contents of The Cryptogram from 1932 to 2009. For information on membership benefits and details on how to join see Membership.

2nd Edition PHOENIX Memorial CDROM
A member reported that the links on the index page of the 2nd Edition PHOENIX Memorial CDROM did not work with Acrobat Reader v9. It turned out to be caused by the default value of a preference option. Here is how it was corrected:
Documents->View Documents in PDF/A mode: NEVER
From the Edit menu, select "Preferences", then choose to look under Category "Documents".
The option "View Documents in PDF/A mode" should be changed to "Never".
FBI Code Breaking Challenge.
The FBI has a website with a code breaking challenge. Check it out.
THE RAT has made available for ACA members a program called Conmaker. It is designed for Windows users to easily create and submit cons to the ACA column editors. If interested, go to the Members Area / Downloads and get your copy.
2016 ACA Annual Convention Dallas/Fort Worth, Irving, TX
ACA’s 2016 convention will take place in Irving, TX, September 9-11, 2016. Your hostess, HONEYBEE (email@example.com), is making arrangements and plans to ensure this is a most pleasurable and enlightening event. Get your cowboy hat and boots ready for a boot-scooting good time!
We hope you will join fellow members of the Krewe in this opportunity to meet and interact with others who share your enjoyment of what is admittedly a pretty specialized area of interest. Come and share your knowledge of cryptology—from historical aspects to solving methods—with fellow members. During your visit, take advantage of the opportunity to do some sightseeing in the Dallas/Fort Worth area.
For those wanting to arrive up to three days before or stay three days after the convention, there is a negotiated rate of $99.00 per night (plus taxes) for September 6-8 and 12-14, 2016.
