What is The FRONTLINE PIONEER ?

its something like a role, which is given to random people/people who signed up for FP, people who are frontline pioneers receive the right to test stuff before everyone else.

and when will be my turn too? ))

who knows, its random, either sign up and hope, or wait for a while, i don't know for how much exactly though

Where do i sign up? cant find it

You will get invited based on your activity, just keep playing and wait.
