It should be remembered that one does not have to be a registered member to read the forum. A portion of the recorded reads will always be non-members.
Also note that the number of "Reads" really only means number of hits on that page. One may open a topic and find that it's not what they were looking for or it's not interesting enough to hold their attention to actually read it, and move on to another topic, but it still counts as a read.
