Designer's Note: This is the mightiest flowchart I have ever encountered let alone tried to develop. There are (obviously) 100 end points and over 325 decision points. A chart of this size presents a number of readability challenges. For people with lower resolution monitors, netbooks, or tablets, this 3800 x 2300 image is going to a scroll-fest. But it's totally worth it.
Update: Those looking for a printable version of this flowchart will find happiness here. This is a 300 DPI bitmap version that should print nicely on 11x17 tabloid paper. Warning! The file is 26MB compressed and a whopping 173MB when unzipped.
