Empire/Party Multiple table question

[Hambone]

Hey guys,
I read about players playing 4-6 tables, but I'm wondering how you do this on party/empire given the three table max.

I tried to create an empire account with the same netteller email as party but it would not allow me to due to "security concerns". so does this involve setting up either a separate netteller account or changing emails?

Right now I play three tables comfortably and would love to add one or two more.

Thanks.
