You are connected to a TEST server.
This server is used for development work only and no matter what you see on the screen you should ignore it.
You may be assured that no orders, memos, payments, or any other activity that may be currently under test will actually happen. On the other hand, do you really want to disclose your name, address, e-mail, credit card data or other personal data when you don't know what use might be made of it?
I didn't think so!
