I found this plugin for wordpress.

http://adambrown.info/b/widgets/2008/02/20/new-plugin-kb-new-posts/

It places a cookie and then marks all post since the last visit with “new”. It seems to be a simple plugin and I think it must be posible to make it work for BBpress2.0 posts.

Can someone give me a clue?
