I stumbled upon a wonderful site the other day. It's called Teen Ink, which is a magazine that is written for teens by teens.
From The Site:
Whether you're interested in poetry, sports, movie reviews or fiction, there's something inside for you. Find out what other teens across the country are thinking, writing and creating - then send us your work and let your voice be heard!
These are some of these month's articles:
Fiction: Writer's Block (Which I really liked)
Opinion: So Long, Wonder Years.
And you can find a lot of other things. Since its a magazine you can subscribe or just read it online. Your choice.
Now I really gotta go, see ya guys!
