Sending bulletins. #Once you've built a network of MySpace friends, the ability to send MySpace bulletins is a powerful tool. Your message won't be e-mailed like your personal messages are, but its headline will appear on all your friends' home pages in the box labeled My Bulletin Space. Whether you have two dozen MySpace friends or 20,000, the ability to let them all know about your new book at the same time is a unique tool.

To post a bulletin, click the Post bulletin link in the box labeled # My Mail#.

Like personal messages, bulletins are a feature you'll want to use sparingly, to preserve their impact. If you bombard friends with frequent bulletins that aren't compelling, they'll start ignoring them, and perhaps be irritated enough to drop you as a friend.

Here are the kinds of noteworthy events you'll want to send bulletins about:

Your new book becomes available for sale at online retailers or local bookstores.

You get profiled in a national newspaper or magazine.

You've won a prestigious award or literary prize.

You've just been booked to appear on The Oprah Winfrey Show _ or _Larry King Live.
