I got the thanks for your feedback email... This "Please note that all the information “Weekly Worker Activity Report” contained is available on your Worker dashboard, which you can review here:
https://worker.mturk.com/dashboard" is ridiculous. All of the information for 45 days is available, sure... and we just have to work out which days are what week, add up whatever earnings it recorded for the days, and then somehow save it so that it looks officially like a record (for those of us who need the proof of income). Or pore through our external, third party database if we've lost whatever section of days we need, if we even have a third party database. Bleh... I have no idea what their real agenda for dumping the reports is, but I don't get the feeling they're going to change their minds. I responded to the email, though...
