Inside the Little Plastic Castle

Following up on yesterday's post, I think I can follow other's peoples' tags using post notifications. I don't think if I can suppress posts.

To follow, I turn on post notifications by example.

1. At a relevant post, click the "alarm" or "track" link.

2. In the pop-up "email me when" click the "more options" button

3. At the resulting "Manage Message Settings" screen, the bottom offers
Track Entries to this Journal
Notify me in my DW Inbox when
One of the options will show
$name_of_journal posts a new entry tagged and then pick a tag from the dropdown menu.

Is this correct? Is there a way to suppress a post based on its tags?
