Please tell me about the different types of leveling sytems

From my observations as a moderator here (I moderate the Toy Hauler forum), the quickest way to infuriate someone is to answer their question with "Use the Search". The state of mind that folks are in when they ask a question is not at all suited for that kind of teaching. The Socratic method has its place, but it typically isn't very successful in these forums. At least that's been my experience.
