Or is that against the rules? I ask this because I have been teaching my brother how to play using my account and he wants his own now. Obviously we would share the same IP since we live in the same house, and I am not sure what your stance on multiple accounts on one IP is since there are people who could create dozens as multis. So my question is: is it ok or not? If so, then I think he will buy premium. If not, then I guess I will just keep letting him take my turns. Thanks!
EDIT:
I think I found what I was looking for in another thread. Apparently it is ok as long as we don't play games with or against each other? LOL, I sooooo wanted to kick his ass at 1v1s. Oh well at least he won't be messing up my games any more.

Anyway, I'd still like comfirmation though just to be sure.
