We may have to think about that for a couple of weeks before we answer. . .
By the way, the old Nff site has a button to "Mark as Read" all the newly-contributed-to categories. I do usually read through all the new stuff, but there are times when it is useful to mark everything as "read." Is it possible to put that button on the screen that shows all Unread items? (I know it is at the main screen. . . I am thinking of the screen after you hit the buttom for New stuff.)
