Not a client, but a boss:
I am a curriculum designer working for a small company. I WRITE textbooks and workbooks. I don't lay them out or anything like that. I make the content.
I know very, very little about web design. But because they both have "design" in the title, guess what my boss thinks I should be able to do?
He has me DESIGNING a new logo and website for his company. While he writes workbooks because "they have to get done!" I suppose the idea of letting the writer make the workbooks and HIRING someone qualified to do the artistic stuff is just too out there for him.
I can't wait to quit this job.
