Thanks for this advice Mike. I'd forgotten about the cfcdev mailing
list, I'll go sign up for that now. Fortunately for me, this site is
not a high traffic site. These are back end business process tools, so
I'm really refactoring to increase the sensibility and maintainability
of the code. I will hopefully also be getting some other developer
resources on this project in the future and they will likely be either
C# or Java guys, so moving to a more OO framework will make it easier
to bring them on I think.
