how does one view replies to messages on this list?

A really newbie question! Using Firefox on Fedora 27, I cannot seem to view replies to messages on this forum. I can see that there are replies, but I cannot view them. Using "browser" on Android on an Asus Transformer, I cannot see them either. If I ask to dowload the message, I get a gzipped mbox that includes the replies. That's not an ideal way to read them.
