That's much more clear, thanks. It's as good a model as any for me, though, as always, I prefer to have a big flying exclamation point as an emotional marker, something I can lay my hands on.

Subscription only sends email if a new post arrives; it doesn't help navigation, though, which is why I always try to include a quote so people know what I'm responding to. If you click on 'thread tools', you'll see 'subscribe' if you still want to.

The thing that helps me most is the 'view first unread' at the top of the thread page. I think you have to be logged on to use either.
