This Miss Wow stuff is BULL. I've tracked some of these girls and it seems to be arbitrary, This lovely
78279 has got 133 letters in 6 weeks an average of 3 letters per day. Seems to me girl gets the bulk of their letters when they first appear. I choose to call them Miss Wannabe's.
The lovely 52852 is Miss Wow because she has averaged less than 2 letters per day for 536 days. Mind you she joined 1 1/2 years ago and if she still has got guys writing to her that long, its their problem.
My feeling it is this sites way of showcasing women so that guys will keep correspondence to girls, even the older ones.
