Anyone who uses a design or layout program whether for web or print will undoubtedly at some point be using the program's font / type functions.

Well even as a novice, after a little digging around Photoshop, Illustrator, Quark, Indesign etc., you find menus and pallets full of options for generating, and formatting type.
Many of us understand enough to get by and rarely delve much deeper than changing font, size and colour.
