I decided to stop waiting for the site’s programmer to finish converting the site over to Smarty. I learned PHP and MySQL and finished the conversion myself. I had trouble here and there (the original programmer didn’t comment his code), but I managed to get it done.
I also fixed a few problems. For one thing, I updated the search function to include companies. I also sped up the person information pages by examining the MySQL queries. Sometimes, the person pages loaded so slowly they would time out. Now they load almost instantaneously, so it makes a huge difference.
