is it possible to subscribe to a thread without posting on it?
Go to the thread to which you wish to subscribe and click on the little pulldown menu entitled "Thread Tools." It's on the toolbar at the top of the first post. Then click on "Subscribe to This Thread."
That is odd as all I see is a selection for a printable version of the thread, not "Subscribe to This Thread".

Well this is really strange, now I see what was mentioned by CaptainMidnight... please disregard my previous entry.
