Well the post is important if you apply on a campaign but really in post if you have 100 post you're still in a newbie rank.. why? because it is based on your activity the activity is the one who will be updated in 2 weeks by 14 activities now you have 28 the rank is really based on what your activity is and you should really notice it by now because on that activity it has a lower number than your post so if you really want to rank up just check always your activity how much is it but i think the jr. member is 35 or more for you to rank up
