As the last full refresh of mzonline.com was fully thirteen years (!?!) ago, ca. 2006, one can say it was time for something new.
I'm super glad I had built the old site out with a tableless and (for its time) clean and well-structured design. While it's been a bit dated for several years, with the exception of the site itself not being terribly responsive (for mobile and alternate screen sizes) it's had a good run.
