Don't panic, I'm not suggesting that every senior pastor or church leader drop the website creation and maintenance service they use, get a Mac; learn html, Dreamweaver, and Photoshop. The current service you use may be working out fine and if you have an affinity for the Mac and high-end graphics you are most likely comfortable in your work. I'm not trying to change that, but to challenge you to learn more about the process if you've been primarily delegating your website creation to others.
