For those of you asking about genealogy, I forgot to mention, if you have any Jewish background - or think you might, be sure to check out JewishGen - The Home of Jewish Genealogy and http:yadvashem.org.il. The latter is mostly Holocaust records.
One other - no matter what your background - check out Italian Genealogical Group/. Their records cover far more than Italian records, particularly if your family lives or ever lived in New York City, no matter what religion or nationality. I discovered several of my family records at that site. Most immigrants to the US during the late 19th & early 20th century lived at one time or another in New York City.
