Mark posts?

Wondering if there is a way to mark posts a person is watching.

I'll be interested in a few posts, following them etc. Then, it takes me forever to find them again.

I know I can subscribe "if" I post, looking for ways for ones I'm just reading.

Thanks in advance.

If you look at the top of the thread just above the first post you'll see a drop down for "Thread Tools". There you can subscribe to a thread without posting. It's not a one-step click, though. You'll have to "Add Subscription" on the next page.
