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.
This script was archived from http://userscripts-mirror.org/scripts/show/341564
Script Name: AA Time
Last update Feb 6, 2014 — Installed 178 times.
Script Summary: Shows AA time when you expand a HIT in the search.
All credit goes to mmmturkeybacon for the time display and helping me puzzle this stuff out.
Note from Clickhappier: This userscript shows each HIT's auto-approval (AA) time setting in HIT search results listings. Related scripts include mmmturkeybacon Enhanced HIT Information Capsule and mTurk - Show Auto-App time & Link Turkopticon to display the AA time on HIT preview pages, and mmmturkeybacon Save Automatic Approval Time to save the AA times for each HIT on the daily status pages.
For many more MTurk-related userscripts, see the Turking Scripts set.
