Creating an FAQ for things like that is a good idea, and I do remember it being attempted at one point. The problem is, it would take a lot of time.
If we were to reinstate a FAQ with complete instruction that go into heavy detail, it should probably be in a prominent place, and all forum veterans/regulars should know about it and use it. I would gladly post the link to the FAQ if there was one. Most of the math questions are usually answered by the time I get to them, or I just don't want to take the time to type out all the steps and explain it to someone.
One adverse effect may be that the number of new topics would go down.
Now, where is Mitch? We've yet to hear his opinion/final ruling.
