It would be great to arrive at the forum page and just click new posts (which is a common forum script feature) and arrive at a page that lists just the new forum posts.
If you are looking for a more involved forum then it would maybe good to find someone to design a bridge to link with phpbb3 for example. Oxwall is a written from scratch light forum which integrates well into the package.
I would love to see a bridge created just to play. Implementing it to the newsfeed etc would be a pain! In time I reckon you will get the options but is is still new in internet world!
