...but I'm partial to Figment.com. I still post on the Pit as well, but individual fics tend to drown in there.
Not sure there is one. by

Every site I've ever been on, with very, very occasional exceptions (such as this one), require an email to have an account, and a registered account in order to post content. If you're just trying to avoid putting your own email address up, I recommend getting a Gmail account for the purpose of "Signing Up For Things." It's what I did, a while back.
That said, my favorite site for posting and reading is AO3, but the Pit of Voles remains popular with a lot of folks.
