Posting in classifieds section

I have tried posting in the classifieds section, but it never allows me. As I understand the requirement is 100 post count minimum (it also says that near the classifieds link), which I clearly have met. When i do try to post it says I need to go premium (pay).

Am I missing something? or dpoing something wrong? Or is the infor on the website regarding classifieds out of date? any help is appreciated
