YWS used to have an age cap of 22 or 25, but really as long as you're at least 13 years old, and you're aware that this site is for younger writers, you'll be good. We're not about to ban you for being 20. ;D
We have members nearing 30, including our admin! But don't be intimidated; they often have just as much to learn as those who are 13. We all help each other out.
A writer is a world trapped in a person— Victor Hugo
Ink is blood. Paper is bandages. The wounded press books to their heart to know they're not alone.
It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small. — Neil Armstrong
