Don't take anything anybody says seriously. You don't know if they are joking about it or are just mean cock suckers if you don't know them. I'm only 15, but I know it's better off just being cool with everyone instead of giving them an excuse to rat on you for having a seperate 'kiddie' forum or being younger than they are. People might say stuff that offends you, but that's cause they try and do it during their spare time as a lifelong hobby.
Make another site if you want, cause that seems like it's what you want to do, but don't expect it to be as big as newschoolers and if you are that young, and your site gets bigger, think about how much you will have to pay....ALOT and as a younger person, you prolly dun have the money to support that. Of course, that's if you make the site AND it gets that big...
My suggestion to you is just to stay on NS, even though some of the stuff on here is for people older than you, you can still find something or somebody worth talking to.
Skiing is not for the simple minded, that's why they invented the snowboard.
