Conquer Club

hi, I'm from Argentina and just started to play this game a few days ago.
My brother wants to try it too. (he has already an account "Folken").
we both use the same computer.

Is that allowed? or is against the rules?

It's allowed if in public games you treat each other like every other player and don't play standard games as team games.
I think it's suggested to play only team and 1v1 games when you are in the same game but it's not compulsory.
Just make sure that you treat him like any other player when playing together in singles.

Thanks amazzony
