I think they're going to add an "Alias" option in the game so you can choose a name to use other than your acct name.

For the moment, you have to do this. 

Launch your IMPULSE, and wait for it to connect & identify your Account (there's a temporary, swirling icon in the top-right corner : it disappears when the account connection has been established).

Go to COMMUNITY.

Click ACCOUNT.

Click LOGIN. There, to the right, you will see how to change your Account's nick. 

Then, when you log-in DG's Internet Game, you will have to type that new nick, and you should then be identified in DG Internet games by this new nick.

Possible problems 

1. The nick change from Impulse to DG/Internet might take some time to be recognized by the latter ;

2. On other threads, some users have complained that they can log in with the new Account name, but that they are still identified by their old nick in the setup lobby and the MP games. I don't know if that issue has been fixed yet for everyone : it was fixed for me on 24 April.

I think it worked for the internet posts...but not in game.....maybe create a new profile?

*edit* yeah it worked for internet posts
