When you are going to be trainee then you can wear a tag before your nickname, heres example: [VU_T]desfire97
Once you get promoted you will be rookie, that means you can use [VU_R] tag, so ur nickname will be like this: [VU_R]desfire97 and if you really wanna stay with us, VU and you are good enough, you will be promoted to [VU] which means you can use a tag what i am using: [VU]desfire97
