Whenever I'm currently logged on to TB and browsing around I get email notifications for every single alert that comes up. This really isn't necessary; I can see the alerts at the top right of the page, I don't need to get emails about them. The flipside to that is when I subscribe to a thread and request email notification I often don't get any and when I come back to TB next time I see a long list of alerts that I was never notified of. This behavior is the opposite of what it should be. Notify me when I'm NOT on TB and turn them off when I'm ON TB. That's how it should work.
