How can I navigate on this website to the latest post? I would like to read only the posts that I have not read previously. Since I know of no way to mark the last posting I've read, I thought it would save me paging thru all the old posts I've already read if there were a command I could use to get to the latest post. It would be best if posts were numbered. Then I would know where to go the next time I wanted to read postings, except this may not be possible because the postings are organized by topic. Any suggestions?
