Yup, I'd recommend letting Mark know, Cricket.

You can check "Active Topics" at the top of the page for different ways to check threads, and you can mark threads as ones you want to watch by checking near (but not at) the top of the page under "Topic Options," then selecting "Add topic to your watched topics."

I don't know of any automatic listing of updates to a thread that you posted on here, but I'm not an expert...
