Laughing Bear,
Although we can decide what we want as a group, we also want to be taken serioulsly. I don't think it would be a good idea to set an age and then start making exceptions for certain minors that we like as this would be very subjective. It could easily end up hurting a minors feelings and could also be viewed as a way to influce the vote on a particular issue. I think we need to come up to an age that we can all live with and then stick to it. It is easier to explain to a kid that they are under the age, than to explain that we made an exception in the case of that other kid because his parent is a dedicated member, we feel that they are more responsible, or we liked them better.
However, as Matt is so far the only minor in question I think your point is that we should consider his age before making a decission. I will try and find out and get back to you all.
