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.
Script Name: MTurk Worst Case Rating *Updated for new Dashboard*
Last update Apr 4, 2014 — Installed 695 times.
Script Summary: Shows potential approval rating in worst case scenarios. *This is a patched version of ThirdClassInternationalMasterTurker's original script to get it working with new dashboard. He last updated in 2012 and the script has been broken since the new MTurk dashboard update.* I will not be updating this version, it was just a quick patch for anyone who wanted it. I uploaded a new script that combines Best & Worst case scenarios into one nice script. I will be working on this from now on: userscripts-mirror.org/scripts/show/449358 [ archival copy had previously been available from swole_hamster at https://greasyfork.org/en/scripts/902-mturk-worst-best-case-scenario ; he deleted his copy on 01-21-2015, so I reuploaded it at https://greasyfork.org/en/scripts/7589-mturk-worst-best-case-scenario ]
