The first step in using Facebook is to sign up and get a new Facebook account. Go to www.facebook.com and fill out the "Sign Up" form on the right. You should give your real first and last name along with your email address and the rest of the form. Click the green "sign up" button at the bottom when you're done.
Facebook will send a message to the email address you provided with a link asking you to confirm your email address. You'll need to do this if you want full access to Facebook's features.
If you're signing up to create a business or product-related page on Facebook, click the link below the sign up form that says "create a page for a celebrity, band, or business" and fill out that sign up form instead.
