Avoid underlined type
Italic type is correct for titles of books and such, and can also be used to add emphasis. Bold type adds even more emphasis, but use it sparingly. If you must underline type, make sure the line does not run through descenders. Underlined type for a web or email address indicates a hot link. You can't link to the web from a piece of paper, so you don't have to underline these in print. On the web, do not underline type unless it does link to something.
