Change in the contest rules

I think that I need to change the rules - after the first comment - people might just "gasp" copy each others answer....hmmmm.....what to do? New rules - post a comment - anything - about the cards and then email your answer to carrie@shockware.com. So you still have to comment - just don't put your answer out there for everyone to steal! I might be overthinking this but...it is just my competitive nature!
