That takes me to the first post in the thread, not the latest.
What is very useful on most forums I frequent, is the link that shows a list of all posts since I last visited the forum, along with a link to the latest post in each thread.
I gives me a way to follow anything new in seconds, without having to load a bunch of pages, and scroll down on each.
That feature would be very useful here as well.
I feel the frustration, I hate the new look.
But here is how I accomplish what your trying to do..
When you first log in click on "Ziller Generac Forums" tab near the top left of the page.
It appears already to be selected because it's white where the other tabs are blue. Click it anyways.
Now right below "Ziller Generac Forums" tab you will see "New Topics" Click "New Topics" and it will list all the new forums since your last log-in.
Now when you click one of the new topics since last log-in you will continue to see "New Topics" near the top of each page. Clicking "New Topics" again it will take you back to the list of new topics since last log-in minus the last topic you read.
The issue appears to have something to do with the page not recognizing you when you return to the page because when I return to the Ziller Forum it shows in the top right corner "Login or Signup" After clicking the "Ziller Generac Forums" tab it then shows I'm logged in.
Hope this helps.
