On a tangentially related note, would it be feasible to get GEDmatch to provide an anonymized/tokenized URL for one-to-one comparisons? The privacy problem for Wikitree is that the comparison URL includes the GEDmatch ID, a unique identifier, of each tester. That means we can't use it for a non-Wikitree member tester. If the URL to compare two GEDmatch IDs couldn't be decoded without being logged into GEDmatch, then it gets the identifier off of Wikitree's system and onto GEDmatch where everyone has agreed to their terms. Then the anonymized URL could be included in DNA confirmation statements. Just whistling in the dark.
