Jim,

No worries.  You can be like the football fan who misses a game and watches it on tape 
delay, i.e., you can still look at the file next week but just resist reading my answer  
until afterwards.

Also, there will be a follow-on contest on the epw format that might be more up your 
alley.  I haven't decided yet whether to post that on Friday or next Monday.
