Welcome to “The Fray,” Slate's reader forum. We've recently made some changes to the site. To post messages in the Fray, Partner Account on the Microsoft® Passport Network. (Why?) You also need a Partner Account to use the Block feature (What's that?) Sign up for a Partner Account on the Passport Network here. (If you have a Hotmail or MSN account, you already have one.) If you already have a Partner Account, sign in now. After signing in, you'll be asked to create a Fray nickname.
