Not sure what you are alluding to with your mention about number of posts, but since you dont seem to understand, under a handle a number of posts is indicated. This is not about how many posts you have personnaly put up, but is a total of the posts you have created and the all responces in all the threads you have started.
It is possible to only start one or two interesting threads, and have 100 posts under your handle if you got that many replys.
(of course, I doubt you would understand about starting "interesting threads")
