History

I've played some other MMO's before that were BIG when talking on forums, and one thing that they do that I'm not to sure you have here is a history. What I mean by that is when I leave a comment somewhere or check something out or w.e, I have a recorded history of it ( just like a purchase history ) that way I can go back to it when ever I want and it's easier to navigate through other than just surfing it up all over again ;p. Imagine leaving a comment on a thread, 12k posts later and you can't find where yours was? :\ (I'm still pretty noob at this so if this feature is there, fill free to take this down >_>)
