I just learned about the "MyHeritage" genealgoy site a few days ago from reading an article on Randy Seaver's blog. You can read his article here: http://randysmusings.blogspot.com/2007/06/visiting-myheritage-data-portal.html#links .
I don't know how many people already knew about this site, but this was the first time I heard about. I didn't post anything on this website earlier because I was testing out the site. This site has a search engine that will search for a surname and up to ten variations of that surname that are listed on genealogy sites. The engine simplifies searching for genealogy information by only looking at genealogy websites. In order to use that search you have to register and download a program that will enable you to carry out the search. The search may take a while to complete as it is searching a very large number of genealogy websites, and it may take longer to finish if your computer runs slow. Unfortunately, my computer runs slow and everytime I tried to do a search my computer froze. So, I really have not been able to truly test this site out, which is frustrating to me. So, you may want to keep in mind if you do decied to use this search engine, your computer may run slow.
Of course there is more to this site than the search engine; I just haven't had chance to check out the rest of the site as a result of the problems I have had with my computer. If you are interested, here is the link to the site: http://www.myheritage.com/
