I get an email that someone has replied to a topic.  I click "reply", it takes me to a page that shows me my original post(but nothing else) with a link showing "4 replies".  I click said link that just takes me back to the page only showing the original post.  I then click "All discussions" and see the post, and click the "View all 4 replies" and, again, it takes me back to only seeing the original post.  So the notification email is the only way I'm able to see what the reply text was.
