5 years? Been running SMF for nearly 11 years here
But, speaking as someone who was actually on the SMF dev team, SMF used to have a more thorough help system integrated into it. It was removed because it was out of date, inaccurate and frankly the wiki does a much better job of it by allowing more people to work on things, keeping it up to date as new problems get new solutions.
Kindred's been around long enough to know most things, and he is generally right. The problems arise when things get very, very complicated and when the usual rules don't apply, but this is not one of those times.
