I am a member of another site that uses Vbulletin and the set up of that site has it so that I am able to see all new threads that I have not viewed regardless of how long it has been. I can click a hyperlink to mark forums read if I want, but this way I don't miss out as I do like to see all the threads I have not "perused". Currently, it appears this site marks posts as viewed by me automatically based on time. Additionally, if I post to a thread, it shows up to me as new posts and the other set up does not show it as new posts for the person that last posted. (I think I am talking in circles).
Is this something I can change, or is it a system wide parameter that could be considered?
