OK, this has NOTHING to do with Crossfires, but I came across this site referenced in a magazine article.

It's www.geni.com. It is a web site for family trees (genealogy). You login, create some family - it's really easy - enter thier info, including email addresses, and invite them to join.

It's a combination of social networking - for extended family - and genealogy. It pretty sweet. My tree has over 260 people in it already! Unfortunately, most of them are dead. LOL, but that's the nature of geneaology.
