You mean a separate page to see all the new posts? Or do you mean that the new posts in a forum are not obvious?
For the 2nd case - look to the left, the icon colour (red) means there's a new post.
For the 1st case - that actually duplicates with "View New Posts". However, I know what you mean. I'll think about this. There are various ways to do this and I need to think about what's the best way. Also, the main browsers now already have RSS (live feed or live bookmarks) support, so that might be one way to do it - enable them to get livefeeds rather than build a new page. The forum should be as lean as possible, is the way I look at it.
Sometimes, things should be offloaded from the server and given back to the user to use his/her browser's features. That's good for the user as well because it means he/she learns something that can be used everywhere.
I promise you I'll think this over though.
