Yes, there is nothing stopping me from entering that ID, but my concern is about the increasing number of people who are trying to use Wikitree's DNA features and hitting a brick wall -- and are expressing frustration here in G2G, asking for mentor assistance, or possibly just giving up.
Suppose I want to see if I have a DNA match with a person whose DNA test appears on https://www.wikitree.com/wiki/Bryan-54 . A couple of the testees there show Gedmatch Genesis ID numbers. If I click on one of those IDs, I am taken to a login page on www.gedmatch.com, and after I log in I see the following error message:
Kit number HD8419681 not found in public DNA database.
Did you forget the letter prefix for your kit number ('T' for FTDNA, 'M' for 23andMe, 'A' for Ancestry.Com)?
If you have just uploaded your data, please allow a few days for batch processing to complete.
Halt.
Nary a hint that I might have entered a Genesis ID number, and that I ought to go to the Genesis site. I know that the ID I entered was a Genesis ID, but not all users of this website can be expected to have that knowledge.
The WikiTree hyperlinking feature gives the impression that it is taking me to a page where I can quickly compare my data with the person whose ID number I clicked on, but in fact the link takes me to an error message. Instead, I need to go to a different website, log in, find the Beta One-to-Many link, type the 9-character ID number that I clicked on back at Wikitree into a box, and hit a button that says "SEARCH."
