Young Writers Society

The Young Writers Society is a website/forum dedicated to improving the writing skills of people ages 13-25. They have many features, such as:
 * Forums where you can discuss writing, review the works of others, and post your own stories. Note that the writing section operates on a 2:1 policy, meaning that you must review two works for every one you submit.
 * A Knowledge Base filled with guides made by members to improve your writing.
 * An "Advanced Critique" forum where you can request an thorough critique of your work. However, you must do the same for others before you can request your own.
 * Joinable groups about certain aspects of writing or about certain books and series.
