I mean the 3 threads that you linked would take a extreme amount of time to do so, I do not see why I would have to research 3 hours into just providing a list of contents or script or hidden features, a system like the one seen in stackexchange would seem more useful as it would be easily used in ever corner of bitcointalk I know it can be done from having owned forums myself back in 2011-2013. Not everyone has the time to make such insightful post on bitcointalk itself.
