I don't know if I'm correct but I think that the number means total people using this whole site... up on the very top there is a list of places-- "Home", "Resources", "Disorders", "Quizzes"... etc.. etc... so I believe that it's the total number of people using the whole site--- not just the number of people reading the forum...... at least I think that's how it is... maybe I'm wrong though??
I often have to ignore that part that shows number of people-- I tend to get too paranoid so I try to ignore it most times....
