Can you sign into WikiAnswers without a Facebook?

You don't need Facebook . . . if you already have an Answers.com account.

The skinny is that a new contributor who has not previously signed up, finds, when he attempts to sign up for an account with WikiAnswers, that WikiAnswers gives him only one mechanism for signing up. That mechanism is to use Facebook's signup mechanism.

Create a new account on your computer, use a different browser, or try incognito mode in google Chrome, when not already in incognito mode.

Then try to sign In to Answers.com. You will have only two choices: Sign in with your already existing Answers.com account, or sign in with Facebook.

There is no option for creating an Answers,com membership from scratch. If you don't have a "grandfathered" Answers.com membership, your only option is to sign in with Facebook. And to do so, you must either have, or must create, a Facebook account.
