I was also shocked by the total on line stat: There are currently 16875 users online.
Now I am wishing I'd recorded the totals on the days I went on line to post the new word count (having learned that if I went on daily, I got lost in the forums for hours…time better spent writing until the goal is reached, at least.) I seem to remember 60,000-80,000 numbers, but I'm horrid at them.
