Some questions to nobody in particular-
On the reputation page, it says 'reputations from members' and 'reputation from posts'. How in the world do you get a reputation from posts?
And just to make sure- if you subscribe to a forum you receive some sort of notification (I have no idea what, and I'm too lazy to subscribe to one and wait until a post has been made) when there is a new post in that thread or forum, right?
