Thread subscription...

I've been on some forums where you can subscribe to a thread without posting in it--you get email notices when there's a new post to it. I like it because you can follow an interesting thread without having to post.

I'd love to see that on the Cow sometime, if possible. There are so many forums with great stuff in them that it can be hard to remember where you saw a thread that was really interesting/informative that you want to check up on.

Thanks!

Michael.
