bisdak you need to upload your rank images to your server in the ranks folder then go to the admincp and open the rank manager and from there add new rank then put the path of the rank example http://yourstie.cct/forum/images/ranks/admin.gif then save make sure you set if you want to stak rank. amount of post etc.
then once you have all that done the go to the very bottom in the admincp and run maintenace and update ranks..and you should be good to go.
Thats easy...
When adding rank Images, It will say - Stack Ranks ? - Tick Yes
And then go to the User Editor, and tick all the groups you want to be in, after that save, and you will see pics that will tell in which Group you are EXACTLY like on the pic you posted
