3-Digit PIN Code
"Keypad entry similar to my 6-digit password, but more complex. A 3-digit PIN leads user to URL of 'x/y/z.html'. Create several folders, each named from 0 to 9. In each are other similarly named folders. Repeat until you get 3 layers, last being html file. For example, secret page will be something like '5.html' in folder '6' which in turn is in folder '7'. PIN code of 765 leads to that page (ie, URL=""7/6/5.html"")."
