I don't know if it's just my computer, but when I click New Posts I get the list of new posts okay, but when I also click Recent Posts (down on the page number line) I get more posts. I think I've missed a lot of posts because I've just been clicking New Posts. I noticed this after a couple of my posts didn't appear when I clicked New Posts. After I clicked Recent Posts they showed up. I would think Recent Posts would be included in New Posts. Does this happen to anyone else? Maybe I'm just not understanding.
New Posts will include those (outside of the game section) that have posts that you haven't read. Recent Posts will list posts, whether you've read them already or not, in chronological order beginning with the most recent. I usually check New Posts and only check Recent Posts when I am looking for a recent post that I have already read.
