In a FAQ (Frequently Answered Questions), people usually expect answers to the questions they might ask. Ubuntu is taking things to a new level there and simply repeats the question, adding a new one in the end:
Question: Ubuntu One Client FAQ #588: "My Account says that I have had an account for x months. What does this mean?"
Answer: The My Account page says that I have had an account for x months. This is confusing. What does it mean? Does this represent the age of my subscription?
Thanks for clarifying, Matt Griffin!
