When I first started on the new forum, I wanted to observe all posts. Guess you know the reason why. Anyway, I clicked on the link that would do this for me. However, the link contained numbers and that threw me off, way off. It, like JSG said, showed me the same posts with some new one scattered about. After looking at the URL, I figured that the numbers were changing but not the way I was expecting. So I got rid of the numbers in my bookmark and now I see everything.
An example...
This is the link I bookmarked - xxx://forums.sailboatowners.com/whats-new/posts/157873/ - Note the "157873", it is dynamic and messed me up.
This is the link I now bookmark - xxx://forums.sailboatowners.com/whats-new/posts/ - Note no number and now I get a fresh page with the most current posts.
I am just posting this so others will see what possibly is their issue, not saying the OP had this problem.
