This can easily be done by going to..
Admin Panel > Users & Groups > Ranks > Rank Administration
Choose 'Add new rank', Fill in your rank title, make sure 'Set as Special Rank' is set to 'no', fill in the 'Minimum Posts' field(ex: 1; User will attain this rank for reaching 1 post), then click save.
After that you can repeat these steps creating more ranks, and when a user reaches the amount of posts you've specified they will achieve that ranking.
