Want to Read the Latest Posting, First!

[Gordmeister]

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?

The latest posts are by date. This is the only way to read latest posts. There is no way to mark posts you have read.
