All of the information to answer the questions people ask frequently is already very readily available, via numerous stickies; primarily the "Useful Links" sticky, as well as my own Modding Guide, or the Tribute Site "Other guides" page. If they aren't smart enough to find any of those, it seems unlikely to me that another sticky or video or something is going to be of any help to them.
Same with the search function, telling them isn't going to do much good because it's already told everywhere and people still ignore it. The primary problem is that people are awful and will continue to be so no matter what your desire to change them.
