Thanks, that is good to hear. I've been thinking about that for a while, about what will happen to our trees and if we are ever faced with a situation whereby we can no longer contribute, etc and no activity or contributions are being registered.
I've been trying to get immediate family involved and my daughter is a 'Family Member' on here. She is interested, but doesn't really have the interest on the level I do and not as active. But then she's only in her early 20s and busy with University life, etc. I told her to register, because it's something she might like to show her children one day, or a curious grandchild and one day in the future, when older, she might herself become more interested in the project herself.
I think future generations will be lucky in the sense that if they come to Wikitree looking for family, they will find it all here and won't have to look elsewhere. Unfortunately they won't have the fun we all did searching for long lost ancestors, but they won't get the headaches that go with it :)
