Sometimes, due to circumstances beyond your control, your post may seem to vanish into thin air. The Internet is a dangerous place: browsers can crash, network connections can go down just when you click "Publish," or you may just accidentally move on to a new page without realizing you had an unfinished post left behind you.
Luckily, we've got a nifty little feature that can save you from a lot of these cases. Periodically, as you write a post, the text of your post will get saved to a cookie on your browser. That way, even if something crashes, you may still be able to get your text back. Just go back to the posting form and look for the "Recover post" link:
Click that link, and anything that was saved in the browser's cookie will be filled into the posting form. You're saved!
