 *** CODING BEST PRACTICES ***
@@ -128,58 +130,58 @@ The following best practices make code easier to read, easier to maintain,
 and easier to debug.  Consistent use of these guidelines means less guess
 work for developers, which means happier, more productive developers.
 
-* Adhere to "Don't Repeat Yourself" (DRY) principles of code design and 
-organization. If you are copy-and-pasting code YOU ARE DOING SOMETHING WRONG.
-If you find a block of code that you want to use multiple times, make a 
-function.  If you find views that are identical except for a single value,
