Untill 2004 there was a search engine for searching in family trees on the internet. It used gendex.txt files to index thousands of family trees and contained over 60 million person names. Unfortunately Gendex.com went offline in 2004. But there is good news! Now there is FamilyTreeSeeker.com (http://www.familytreeseeker.com). A new search engine using the same gendex files. So if you use a program that can export gendex files (Ged2html, Ged2www, Gedpage, GedBrowser, TNG, PhpGedView, Legacy, etc.) you can submit your tree now. You can already search in over 2.7 million names and it's growing fast.
