I had spent weeks discussing with a client the appropriate features he should look for in a hosting account for the website I'd been designing for him. He was insisting on getting a very expensive package even though it was way beyond anything he would ever need or use. I would have felt guilty if I just let him go on, so I tried one more time....and this time I think he got it.
Client: "How many subdomains will I be able to have with this hosting package?"
Me: "Twenty-five. Are you thinking about expanding?" (I'm thinking...cool... more design business for me.)
Me: "Those are pages. You can have as many pages as will fit into your hosting plan, even thousands of them if you want."
Client: "Those aren't subdomains?"
