How do I follow a thread I don't comment on?

I want to follow the "Diam Earth" thread but don't have anything to add. I bookmarked it, will that inform me via email when something is added to it?

When you are viewing the topic, scroll down to the very bottom of the page, in the left bottom corner (in the blue stripe) is a button to "Subscribe Topic". Click that and the rest should be easy, should notify you via email of any replies

Thanks Spanna

Guess I didn't scroll down far enough.
