Hi John,
Uploading a GEDCOM is part one of adding your GEDCOM to WikiTree. There's a GEDmatches report for you to review and complete and then you can submit your GEDCOM for review by a team member. Once it's approved it's then processed into WikiTree.
Here's the link to your GEDmatches report:

You'll need to complete step 2. If you have any questions, let me know.
Thanks!
Eowyn
