Ed Tittel is a 23-year veteran of the computing industry. After spending his first seven years in harness writing code, Ed switched to the softer side of the business as a trainer and talking head. A freelance writer since 1986, Ed has written hundreds of magazine and Web articles — and worked on over 100 computer books, including numerous For Dummies titles on topics that include several Windows versions, NetWare, HTML, XHTML, and XML. Ed is also Technology Editor for Certification Magazine, writes for numerous TechTarget Web sites, and writes a twice-monthly newsletter, “Must Know News,” for CramSession.com. In his spare time, Ed likes to shoot pool, cook, and spend time with his wife Dina and his son Gregory.
