Question

how do you uplaod dna data

Answer 1

You do not upload raw DNA data to WikiTree. All you need do is go to the drop-down menu under your WikiTree ID and click on "DNA." That will take you to a page where you will be able to add any DNA test you have taken and where it was taken, for example at ancestry.com, 23 and Me, FTDNA.

Answer 2

If you wish to collaborate with your matching DNA cousins then I recommend you change your privacy level to "Private with Public Biography and Family Tree."  If you need to be private then change your first name to W or Anonymous.
