Also, it's not clear to me that when I "watch" a post whether it gets automatically mailed or not. Reviewing it just now, it seems that I have to manually elect to have a thread mailed to me, and it takes quite a few clicks to do this. Seems like it was much easier in older versions that you could simply check off a box when posting or replying, and you'd automatically have posts emailed.
Another good feature (seen in other packages) is that you get one email advising you that the (monitored) post has been undated, but you won't get another email until you check the board. There's no reason you need 10 emails if 10 posts have been made in an hour.
