Customize Notification Settings? (Or forum bookmarks)

I love the game so far! My only criticism is that it seems to lack what is usually a pretty standard feature in any forums environment, where you can either customize your notification settings when you subscribe to a post (usually "Notify me of all replies" "Notify me of replies to me" "Notify me of posts by OP") and/or you can bookmark forum topics. I'd love to be able to do both, ideally; it's a little tedious to get five million replies in a forum when really I just want to be notified if I get a response from the OP. I'd also like to be able to bookmark forum topics for later without having to subscribe to the replies.

For the time being, it's made me hesitant to subscribe to anything, and my browser bookmarks are cluttered up with forums I'd like to refer to later. I'd love to see these features implemented eventually.
