At least in the New Orleans forum, when posts are added, the latest posts are NOT listed as the most recent. So it is impossible to see which threads have new posts. Only way to know is to go all the way to the lowest thread level and check.
It happens at the bottom section of the Nola portion.
Each city, like Lafayette and Lake Charles show the last lady who posted on the main page.
When you open the Lafayette section, there may be 5 ladies that posted after the one shown on the main page.
It's always been like that. I missed a few good chicks who passed through SW La. because of it. I now open them daily to check for who is in any town I am working in.
