Hi M,
To be able to import your GEDCOMs into WikiTree, you'll need to click this link:
http://www.wikitree.com/index.php?title=Special:UploadGedcom&action=report&gu_id=27198
and then complete step #2, which is where you review the GEDCOM, check all the suggested matches, etc. There are directions you can follow to complete that step and when you are done you can click the Approve button at the bottom of the report page. That submits your GEDCOM to be reviewed by a team member. Once it's approved it's then processed into WikiTree.
If you have any questions, let me know!
Eowyn
