I upload my file as a gedcom, once it is on Tribalpages I do not want the source showing to members I invite, can I remove or hide it enmasse or do I do for each person?

Unfortunately you cannot selectively hide the "source" for visitors. In custom privacy settings we do let you pick various fields to hide, but "source" is not one of them. We did not think this would be something one would like to hide. We will take this into consideration for a future release. Thanks
