I'm in. "@Craig Manske"
I am not a paying member of Geni, if that is a problem. I joined back when Geni was still free and though it was a GREAT resource. But since it's gone for pay I've stopped using and updating the service. My current research is far more detailed and much more accurate then what I have here. What I would really like to do is delete EVERYTHING I have here and re-add my gedcom file.
Gedcom is a great tool to off load adat from Geni to other off line personal trees.
It really does the job and a duty for that.
IMHO, however, it should not be possible to upload Gedcom files to Geni, which serves the ultimate purpose of creating a large tree connecting a lot of people world wide.
Whenever (some) people want run a very private tree - a lot of white boxes even for long dead people - I believe they should resort to other, off line software running on their own computers only. That's where Gedcom is a great tool to port data from Geni to Disgen or other similar off line tree software.
