I'm using this 'clickhappier-archive' account to post archival copies of old MTurk-related userscripts from userscripts-mirror.org (which is itself an archive of the defunct site userscripts.org) and forum posts, which their authors or others haven't re-posted on Greasyfork yet. Some of these may no longer be all that interesting as more recent scripts may do what they do better, but some remain very useful.
Note from Clickhappier: I added the necessary change for this older version of HIT Scraper to remain functional after a TO mirror server change that took effect on Oct 27, 2014. But I now recommend using Tjololo's actively-maintained version with additional features, https://greasyfork.org/en/scripts/2002-hit-scraper-with-export , instead of this one. I did use this one for a while, and thought it should be preserved to remember Kerek's original contribution. :-)
