I think there should be a way to mark, or tag a post. (or is there, and I just don't realize it?)
To clarify what I mean, you would find a post that interests you, you post a reply... you want to hear what other people have to say about your post... you don't want an email sent to you, so you click a little button and it marks the post for you, and when you log in it will show a little list of "marked" posts, just like the little PM thing, and you can go see your "marked" posts.
What do you think of this? (I could use this right now....)
