How about the kiddos? Or how about giving everyone a number and have the kiddos choose a number between 1 and 1300+++
But I sure would understand. A random electronic thingy would do the job in a hurry.
Am sure it would be fine any way you choose to do it.
Thanks for all that you do on the site, this is just a little part of that, and I hope it is one you really enjoy.
