Gmail now offering another export solution “Email task list” that can be found in the Actions menu. Clicking on it’ll open a new compose window with the contents of your current task list. This works in all views (my order, sort by date, completed), so you can email and explain why you've been so busy and haven't been able to return her calls, just choose "View completed tasks" from the Actions menu, then "Email task list" and send away. (Note: this may not be very convincing if you haven't actually checked anything off your list recently.)
