Yes, data at GEDMatch can be withdrawn, you have the option whether to show an email address or not, you have the option to give an alias as well as a real name, when only the alias will appear. If you do a 1-to-Many compare you get a list of matches, ordered by total segments in common. Some of these have emails beside the name (or alias), others don't. To contact someone you click on the email address, or copy/paste it. If they don't have one you can't do this. I personally have myself and other family members (whose GEDMatch entries I control) with my email showing, but aliaseas (mostly first names) for all entries but me. You also have the option not to include a person in the public group, meaning they don't show up in the 1-to-many comparison. You still have the option to compare them yourself in 1-to-1 mode, if you know both ID numbers. I am not sure what will change at 1 Dec but there is a notice there explaining it which I can't remember in detail.

Is one required to attach the person's real name to the data? How does the contact system work? Can ancestral surnames be added to the profile so that matches can see them? How much of the data can matches see? Is it possible to restrict access to the data?

Lindsey, no one can see detailed data like SNP's or so if that's your worry. Gedmatch does all the magic for you but only shows the summary data, never detailed data (same as the big 3 testing companies). So no worries Andreas > On 3 Dec 2015, at 06:03, Belinda Dettmann via <genealogy-dna@rootsweb.com> wrote: > > Yes, data at GEDMatch can be withdrawn, you have the option whether to show > an email address or not, you have the option to give an alias as well as a > real name, when only the alias will appear.
