Create a rank:
Administration Panel>>Users & Usergroups>>Ranks>>Rank Administration

To give a rank:
Locate the user you want to have the rank. Then look at the profile in the administration panel. Scroll down to the bottom, there is a option to give a rank: it usually is a drop down menu. Press the Save button when you are finished.
