If I may...
The rule about "no file photos" may want to be considered in a certain light: capturing the existing must be ridden, posting the new tag could be done with a file photo. This will allow your game to run much more quickly since it eliminates the wait period while the winner gets a new tag. Waiting could kill interest that otherwise would have remained fixed. Just a thought 'cause that's how we roll in Buckeye Country and it has worked to everyone's advantage.
Good start to the game, PA

. Have fun.
If all goes well I maybe swinging through your way for a few days in October.
