What is karma?
Karma is the sum of up and down votes on comments and articles you have contributed. An up vote is worth 1 karma point, a down vote -1 point.
How do I submit an article?
You can compose a new article using the Create new article button visible in the top right of the page after you have logged in. You can only submit the article to Less Wrong once you have reached 20 karma points. Prior to that you're welcome to save your work as a draft.
