The SSGT does not provide user accounts. Instead, the SSGT provides a wantlist file as part of a generated subset package that saves your list of selections.
In order to resume work on a subset, this wantlist must be uploaded into the SSGT. Click on Choose File
to select your most recent “wantlist.xml” file, either generated individually or as part of a subset package (zip file).
If you currently have components in your subset, you can choose to either merge or remove them when uploading a wantlist.
