Simple way to do it would be have a team declare at the start of the season or prior to their first competition the following:
1. Team name
2. Team member 1 and their kcbs membership number
3. Team member 2 and their kcbs membership number
5. Other team members can be listed but at least one person in attendance must be a card carrying member of kcbs and present and on the list submitted at the start of competition for any points to be earned.
No person can declare themselves as members of more than one team for TOY purposes.
The only numbers tracked are kcbs membership numbers and must be verified by the above criteria.
