On this site, if I click on the "more replies below current level" message in a thread, the new page displayed shows the same messages as before. The only way to get to these lower-level messages is to back out of the thread, to the list of threads, and click on the "2" or "3". On other sites with a similar interface, clicking on the "more replies below current level" link brings up a new page that includes the next level of replies (i.e., if the first screen shows five levels of replies, the next level shows 10 levels of replies). This is more intuitive than having to back out of the thread in order to see the next level of replies.
