My Followers is the complement feature to My Feeds. Whereas My Feeds allowed you to manage the Ustreamers you are Following, My Followers allows you to manage the Ustreamers who are Following you.
With My Followers, you can send out Bulletins to all of your Followers at once. In addition, you can instantly send your Bulletins to Twitter. Pretty cool, huh?
In the Privacy tab, you can set what notification items get sent out to your Followers.
In Manage, you can Direct Message your Followers individually or choose to “Block” a user. Blocking means that even though the user has chosen to Follow you, he will not receive any of your notifications or see any of your recent activity.
