(Totally off topic; please feel free to ignore. I ask here because I feel asking via email would be even more intrusive.) Are the Matasano Crypto Challenges alive? A friend of mine and I sent (first) requests around a week back, and we haven't heard back yet. I understand that real people respond to these requests (at their leisure, I guess) and so turn-around times would be long, but will somebody eventually look at the requests, or is the program on hold/in limbo?
