Hey ManKind207,
To link your minecraft account with your forums account (MineSync), you will have to do the following:
1- Once in game, do
/hub
2- In the hub, you have to do
/link
3- An alert will pop up, telling you to click on a link so you get the account connected, if you are logged in, once the link is open, you will be given the ranks if you do have them
In the case your ranks dont show up (and you have them in-game), click
here, to manually show a new display group
¡Hope you have a good day!
