Thats right, you would inform the Campaign manager that you ranked up while participating in the campaign so that he would be aware of changing your status and your payrates because if you forgot to remind them maybe your pay rates would remain still in you lower rank because campaign managers are too busy on handling many signature thats why they dont have enough time to 1 by 1 all members just to check their rank, be also a responsible participant. There are also campaigns that are automatic or controlled by bots which dont need to remind the manager because the bot itself will change those rates. Goodluck
