My son turns 8 soon and loves the game. He starts playing next year and I'd like to find an age apporpriate book so he can begin to understand the positions and responsibilities of those positions. Looked at chapters however they seem to be aimed at adults.
I'm thinking the web may be your best bet and save you some mileage as well.
I havn't looked yet but I'm sure there must be enough 'how to' type sites out there to cover most age groups.
If reading off the computer is a problem
(I personally prefer a book) then a half decent printer may be worth the investment.
