Usu and Karyete also were about 10 / 11 years old when they started here. It depends on yourself if you want to be serious with your life in this community and follow common sense, or if you want to be known as a n00b. Your age doesn't imply to us that you would be a n00b, but pointless topics and posts of yours would do. And on the other side, I've also seen significantly older members with bad posting manners.
Try to be nice, try not to be off-topic when posting and try to care about grammar and spelling as good as you can, if this is what you're worrying about. Then we won't care that much about your age.
