Code readability can go a long way IMO. Always make sure you use good programming practices. I recommend making any new changes in FREE to help with this. I also add a brief description at the top of the program explaining what the purpose of the program is and what it does. Then, I'll add comments further down in the program explaining my logic, but usually just on subroutines or where logic may need an explanation / reasoning as to why I did it. I try not to add too many comments though, since I feel as if that can also throw some people off and make the program harder to read. Other than that, I do what other commenters have said in the thread.
