Right now on the main page there's a "Recent Topics" list that lists the recent topics that were posted in.... of course they don't show the actual post but you can at least see the last topics that were posted in (and by whom).
Actually no, nevermind. That just seems to be a list of newest topics? I agree with bwiz, a list of recent posts would be cool. A box just like the recent topics one but "Recent Posts" would be perfect.
Also on the menu bar there's a "New Content" button. I have all the forums marked as read so that page says "No new content" for me, but maybe that page will show posts you haven't read or something.
Sounds cool to me I 3rd this motion. (if that even matters)
