Do NOT use this plug-in unless you are willing to be locked out of your account whenever the company chooses to.
I am removing every testing instance of this plug-in and recommend other do so also (unless, maybe, if you are using a CE installation).
Any company that locks you out of your account with no warning (they claim I exceeded my free 10G, I dispute that) unless you pony up money is un-ethical and has no business being part of a great open-source project like WordPress (or Moodle or Drupal).
