Thanks for the input!  There are some good ideas there :biggrin:  For the regular Challenge Arena Challenge the winner of the previous Challenge chooses the topic.  You are certainly welcome to set up a challenge for anyone interested and manage it as it goes along.  I hope you will join in the April Challenge (topic unknown at this time).  Go to the March thread and vote for your favorite.
