Hud Messenger

Hey, I’v made a simple rank system which shows player rank using hud messenger device which display it till player rank up to another rank, and here is the problem. Whenever player rank up, save device saves player status, but when a player rejoins the game the hud message with a rank won’t show up, because the rank shows only on a ‘class changed’. So here is my question, how can I display a players rank when he rejoin the game? How do I trigger it for every player with a diffrent rank?
