suggestion for marking threads as "favorites"

There is so much good info in the BT forum, and because of the quick turnover of some of the good threads, I'm making a list (in Word) of links to thread "favorites" that I want to save on hand (there's a certain one on HRM training, online tri stores, etc. that I'll probably keep referring back to).

So I wanted to make a suggestion that if there was any way for users to mark threads as favorites through BT and be able to browse our own list, maybe it could be a useful feature.

I could probably just put them in the "My Links" part of my log, but I was thinking it might help to have something a little more out of the way.

Or instead of "favorites" it could even be more generally for ones we want to temporarily save, like ones we've posted in and want to monitor any follow-up comments in response to our posts. (I am always forgetting which ones I've posted in, but like to try to follow those.) Is there a way to toggle email notification if someone "quotes" one of our posts in a thread?

These might be hard to program and I'm not sure there would be an interest, but just wanted to raise some ideas.
