Software
HtmlPedigree
Most of this site was built using HTML Pedigree. This very flexible program automatically produces interactive charts from a gedcom input. I am not aware of any other program that produces such useful output, yet allows the user such a range of control over the finished version. I think it is suitable for users with a wide range of experience. The search facilities on the site are also provided by this program.

Ancestral Quest
Gedcoms for the site were produced from our collaboration databases held in Ancestral Quest. This product allows specified users to access and modify centrally held databases via the internet. We have authorised users in England, Canada, Australia and the USA. As far as we know this feature is unique to Ancestral Quest.
