How do you get ranks in lobby?

I find people having emerald and stuff in lobby, hoowoww!

 

Buy a rank in factions

 

Automatic

 

I have diamond there from Skyblock.

 

Mcmmo ranks don't show up in lobby though. I hope that can be fixed.

 

i thought only factions ranks appear on hub

 

People from facs do have ranks but not all do

 

I have emerald in hub and have access to /fly
