In-game name under profile?

[Harry 18]

I have seen people with their in-game name under their profile.

So my question is how do you add that to you're profile?

When you're whitelisted and play in game!

The ingame name is shown under the Avatar once you log into an RP server.

It used the Player ID that you log in with then updates the forum account.

Edit: Quick and easy question marking as solved

When you join one of the servers with that name it will automatically come up.
