I am looking for a way to increase the duration an item is marked as "new" in a list by up to 30 days.
I found this article, but it is only viable for Sp2007 and I can't find information, if this is applicable to the whole web applicaiton, site collection oder even a single list.
As an alternative I am imagining some sort of conditional formatting, to show the user if he has already opened the listitem. Is there a property which I could use to achieve this?
To break it down: I am looking for a way, to show a user new list entries (unread or up to 30 days old) on a rarely visited site collection, where peripheral information is gathered.
