What are these blue arrows next to the orange envelopes next to updated threads? I know the orange envelopes indicate a an newly posted to thread, so then, what is the blue arrow for? And will the arrow ever point up?
Well, from what I have deduced by clicking on the arrow and seeing what happens, the blue arrow next to a thread takes you to the last post in that thread. The blue arrow next to a user name at the right takes you to the last post by that user.
