As promised, I will never reveal any such information myself, but if you are a submitter to the project and want to put some information about your own ID, it is a good idea to do it in one place. This way, anyone who is interested in some individual's genetic makeup may look up the relevant information.
So, feel free to leave a comment, revealing as little or as much information about the ancestry and background of your ID as you are comfortable with. To reduce the clutter, only posts containing such information will be allowed.
Note: the comments section spans more than one page, so use the links to go back and forth between them.
