I believe that accessing the 'more info' page for a story neither increments my 'stories read today' count, nor does it affect the 'last accessed' timestamp for the story.
I thought that fairly recently the system was altered so that accessing the contents page of a story (the one that is essentially just links to the chapters) does not affect the story count, nor cause it to appear in my history; however, the 'last accessed' field is updated. This seems inconsistent, and means if I, say follow a link in the Lost Stories fourm I lose the ability to find out when I actually read the story! (Instead I have to go to the author's page, find the story, and use the more info tage on the story listing.)
