Join the club, lots of people do. Many genealogists feel pressured to use the internet when they are not familiar with the terms used or the machinery itself.
Computer hackers assume everyone knows what they do and sneer at amateurs.
For Dummies' series will give you the instruction you need to use the Internet profitably in your research. Genealogy Online For Dummies, by Matthew Helm and April Leigh Helm presents the information in a straightforward way, with plenty of examples and advice. The formula tries to instruct without pain, and the Helms have succeeded. I met Matt Helm in Cincinnati recently at the Federation of Genealogical Societies annual conference. He described how he and his wife April came to genealogy when they were very young, after her grandparents left April their research notes as a legacy.
