Leaving comments. #After you become someone's MySpace friend, visit their profile and add a comment. This is an effective networking tool--not only will your new friend read your comment, but people who visit your friend's page will see it, too. Avoid the most overused MySpace comment: "Thanks for the add," which means "thanks for adding me as a friend." It's a clich�, and a missed opportunity. Take a moment to think of a meaningful comment, based on something about your new friend's profile, like "Hey, my favorite author is Hemingway, too!"

Sending messages. #MySpace has an internal e-mail system and an instant-messaging system for sending private notes. You can include your regular e-mail signature, including links and photos. But if the message isn't too personal, you're better off posting your thoughts publicly, as a "comment" on your friend's page. This increases your visibility on MySpace, making it that much easier for new friends and readers to discover you.

Responding to messages. #When you receive a MySpace message, you'll receive an e-mail alert. To network effectively, respond promptly to your messages. If someone makes the effort to write to you, they'll be waiting for a response. Don't alienate potential friends by letting messages pile up unanswered.

Sending personal replies is time-consuming and you won't see instant results. But remember, the personal connection you provide with a thoughtful reply is something readers will remember, and something they're unlikely to get from a big-name author. These are the folks who will feel good about you and recommend your books to others.
