We are two brothers. I work in graphic design and my brother works in data entry. Can we open two accounts and work from the same PC?
As long as you both have totally different payment methods, emails and account names here, you can. You also would have to avoid being in the same categories - you cannot put your Gigs in data entry and he cannot put his in graphic design.
You can always contact customer service and explain what your situation is to get an OK from them, but, you should be able to do this.
I hope your information will be very useful to me.
