As known, if a new users makes several posts, all will withheld in the moderator queue. Well, a users made two posts, I approved one and was going to disapprove the other when I noticed in his profile it showed for posts as having 1 and 1 being in queue but for most active forum, it shows two posts despite only one being approved and the other still in queue.
I made a regular user account and looked at his profile and it still showed two posts in the most active forum. So for active forum a post shouldn't count until it's actually approved/disapproved. I'm not sure about most active topic.
