A bulletin appears in the Bulletin box of each friend on the list. It's not an e-mail; there's no alert, for example, and no deleting other's bulletins. If you have more than a thousand friends, you can't see the bulletins unless you specifically go to the box. For comparison, I have 8000+ friends and each bulletin round brings 40-100 hits, but I post the same ones every few days, so they have slowed down. I don't really do MySpace anymore, apart from having my other window open to it right now (lol) but bulletins to a fresh set of friends can get some attention. Also, the subject line is very important. That's all that gets shown at first.
