Most programs allow you to print reports, charts, etc., making it easy to share and analyze data and perhaps even create your own book. Some, such as Family Tree Maker and Family Origins, will create web pages from the data. Besides websites, there are other internet tools that can assist you. There are also mailing lists for many surnames and locations. Forums are like bulletin boards.
People post queries for the world to see and hopefully answer.
You will need to learn to use search engines to find material online. When looking for a surname, don t just type in the name. You need to add genealogy or perhaps a location to narrow the search. For direct communication, chat rooms allow you exchange information immediately. Once you get your material assembled, you may want to put up your own website so that you can share with others.
