I’d say with the email for registration have it tell them to be as specific as possible.
Questions that go something like “I hear a funny noise, what could it be?” or “my CEL keeps flashing and hasn’t ran right since it started this 3 years ago. What’s wrong?” will make others ask you questions before they give you an answer.
Although, if we linked every FAQ we get on here, we’d pretty much be left with posts by me reposting autoblog articles. 
Also, this has been a VERY friendly forum for new people compared to most others I visit. If we were like those other places when we get those FAQ about octane, acetone, neutral coasting, etc., we’d tell the people to stuff it, search the forums.
