Having said that, both d0gma and I are in a squad that includes a 12 year old. Sondog is a good kid, and getting to be a pretty good stick. One thing he is NOT is any kind of brat -- if it wasnt for his voice, you'd think he was just like any one of the many "good guys" out there. He doesnt smack, cuss, whine --- or squeak.
The issue isnt whether a player is a kid or not. Its whether the player shows maturity, and interest in a game that frankly requires a long attention span.
Some kids don't have either, and don't get the idea that THEY need to expend some effort to learn. Unfortunately, there are also adult players who don't have either, so we can expect that those choice individuals will abuse some kids who don't deserve it.
Worst of all, we can't really do anything about immature kids, or immature adults, except take a deep breath and try to laugh about it.
