I've got a problem. I'm making a website for so and so, and all of a sudden I get an email saying I'll be working with so and so's daughter, because she has a good eye. So and so's daughter is a bit of a designer herself, so I don't mind... except she has no concept of designing for the web. You can't have a menu bar a mile long because not everyone uses a 1600 x 1200 screen resolution. And yet, if I design a website that works on a 1024x786 resolution, she gripes about all of the free space on the sides. I'm not sure what to do... has anyone ever dealt with this sort of situation before, who could offer some advice- basically, a polite way to tell someone to let me do my job, and to $tfu?
