Perhaps next year to help raise money for a good cause you guys could add a new dimension to the hearts. Make it $1 to give a heart (love the low price BTW!) and $5 to take one away from a member?
Then when members get in a spat, instead of tossing insults back and forth they could pay up to yank a heart from the other member! Imagine what that could do to the dollar amount of the final donation!
