Do you want to know your personal Mechanical Turk worker ID? This is the identification used by MTurk to track you when you work on HITs. Amazon recently updated the MTurk API, adding Worker IDs to qualification requests.
The idea behind this, of course, is to keep bad/unqualified workers from resetting their qualification scores. By tagging the qualification data structure, Requesters (the people who pay to put HITs onto MTurk) can see who is requesting what, and thus inform their decisions.
I saw this new API extension as an opportunity to play. I’ve added a new MTurk qualification. It shoots off an automated e-mail with your Worker ID upon granting your qualification request.
Please note that the notification is run on a daemon which is only active when my computer is awake, so it may take a few hours (or days) for your request to process. Also, I’m not sure how long I’ll keep this qualification going–probably at least a couple of weeks depending on the response. There won’t be any HITs associated with this qualification. At least not in the foreseeable future.
UPDATE: Please see this post for an important update. Amazon clarified that they only allow Requester-to-Worker communications where a previous work relationship has already been established. It’s not enough to opt-in for a qualification. You must have an assignment either approved or rejected before a requester can contact you.
