From that page, scroll down to the middle of the page until you see the link that says “Click Here to upload to Ysearch.org.”
This will open a new page in Ysearch.org and will allow you to create a new user ID in Ysearch.org. This page will load your results and make them ready to upload to the Ysearch database.
All you have to do is fill in at the bottom of the page, your Last name, Haplogroup (this can be found from your ftDNA home page by clicking on Haplotree link on the left side of the page),
Which will then pull up a page and display your "predicted Haplogroup"
Next, add your contact information, additional spellings of your surname, and the most distant known paternal ancestor and country of origin.
Then enter a password that you can easily remember, enter the captcha letters and click the “save information” button and you are done!
Make sure to copy down your Ysearch.org user ID and password in a safe place.
