"new" Marker On Forum Section

I have been on the forum for a while and to be honest I have not paid that much attention to this flag. Basically I look in the newbies section to welcome any new members, followed by my watched threads. Once I have reviewed these I then review new posts. I only look at the new posts that interest me and ignore the rest. Each time I review new post it shows the ones that I have not reviewed before along with those that I have not opened. I find this works for me and I get to open and read only the content that I want.
