Welcome! What you do is, if you have a question, start a thread and ask (you knew that), if you have an answer, post it on the right thread. If you know where you got the answer, that's a good thing, and sometimes people need to know. If it's a guess/opinion, that's ok too, but sometimes you have to say it is. If you disagree with something, post that if you want to (why you disagree is good, even if the answer is just that something doesn't sound right). If there's anything you think should be in the Kid's Link, let Max know.
(Here's the dull-but-necessary grownup part; hey, I'm a mom) Naemanson is right, check before you put on anything more personal than what instruments you play, and stuff like that. We're a pretty good bunch here at the 'Cat, but remember, never post anything you wouldn't be willing to tellto the whole universe (or in a school assembly). As you found out, anybody from anywhere in the world can get on the 'Cat and read the threads, including scumbags that might live near you. (That's enough lecturing, hollowfox!)
Anyway, have fun here at the Mudcat Cafe, Mary.
