It saves time to write a Frequently Given Answer just once, and then just post a reference to it every time that a relevant question is asked, rather than soak up large amounts of bandwidth posting the same answer longhand time and again.
The common practice is to refer questioners directly to one or more specific answers, which will themsleves cross-reference the other answers that they relate to, if any. But there are people out there who are terminally inquisitive. To satisfy them, here is a list of all of the FGAs that you can find here, broken down by category.
Feel free to refer people to any of these answers yourself if you need to.
