I've got a bit of an off-topic thing to say...
I think that you guys are sort of ridiculing younger people buy saying 'you are probably only 14 or something' or along those lines. Just because your age is that old doesn't inflict on whether your opinion is right or wrong, whether the info you have given is right or wrong, or anything you say is right or wrong. I'm 14, so therefore a reasonable slice of my peer group is. Alot of my mates are quite knowledgeable, for example most of us can weld, do mechanical work, do fabrication work etc. If we can't do something we learn.
Really what I'm trying to say is, don't flame someone and say 'you are 14 yrs old, you know nothing'. The only difference that sets us apart from you guys is the age and the responsibities.
Sorry if that sounded like I was real pissed off , I wasn't. Its just because I'm part of a stereotypical group.
