[grand-rapids-pm-list] Perl puzzle / Meeting Friday

[Ed Eddington]

Correct Brian! (Both the puzzle and the meeting day being tomorrow. ;-)

However, I did receive correct responses also from Ryan, Derek, Matt, and David. They will have first dibs on the prize.

Hope to see you at the meeting.

Ed
