Hi Aaron,
I think this'll be a good idea - it will keep me checking in at least on a weekly basis. Hopefully it will spur us all on to keep active in the other threads as well.
Yes, this was a nice warm-up. I'll wait until the solution is posted before I make any other comments on it. It might be an idea to have a "spoiler" thread in case people want to post answers, what specific aspects tripped them up, how they "broke in" to that particular cipher, etc. before the solution is officially divulged.
Keep 'em coming! If this will be a true "Code of the Week," would you prefer to have other submissions sent to you off-list and then you can screen and schedule them?
Looking forward to next week!
Angela
