How do I arrange for the preservation and continuity of my site? I want to give instructions to my heirs on how to claim ownership of the site, even though I don't know at present which one of them would be willing to assume its care. (At least two of them are Mac users.)
At a minimum, to mitigate the potential of a site membership problem, be sure to backup often, or export to a GEDCOM file frequently.
Providing your personal computer data is accessible to those heirs; or you backup to a flash drive or something, they'd at least be able to re-create the site by uploading the file to a new subscription.
I know that doesn't cover the SITE's issues, but it's also a good practice!
The same plan I already have. It's time to look for the next genaration. As You know, it's not easy to find a interested successor. I don't have already one, I'm still looking for.
The following thoughts I've and my cousin (the deputy site manager) done.
If we find a willing successor (or two), I promote him/her as a Site manager (in the memberlist, see more... on the specific member). Give him/her the usefull instructions and show/explain him/her our family archive (paperware, originals, photots, etc.). At the effective date I will send an email to the support at firstname.lastname@example.org to change the site owner to the new one.
The minimum two new site managers, and of course the old ones, should comunicate together to prevent standing on the feets of the other.
After this switch, we, my cousin and I, are in the second row and can support the new generation of site owner/site manager. If this switch couldn't be done during the lifetime, the new site manager should send the email with the switch request.
These are my, not complete thoughts. Hope it helps a little bit.
