I am been developing a new application for sharing and collaborating Family Tree/Genealogy information and more. The website is http://my-family-lineage.com/wiki/Main_Page
It is completely free. I have put some effort into allowing GEDCOM files to be imported into the website application so that one would not have to start from scratch. One can manually enter information starting with the name of someone in your family tree.
In order to really benefit from this application, I need to get more users that will share their family trees, or genealogy information. The code automatically generates ancestry charts for each person in a GEDCOM file and mapping information is presented as well. There are fields for documenting the source of the information, as well. I did test some of the software with some public GEDCOM files but it would be great to get more variations of GEDCOM files included in the application.
The software uses some new technologies that are part of the evolution of the Web. This is described in a FAQ on the site. Again, the link ishttp://my-family-lineage.com/wiki/Main_Page
