I just had an email discussion with an administrator who was trying to decide whether to allow people with only a Family Finder test in his project. I shared with him my philosophy - which I repeat here:
A surname project is for yDNA tests of men with the project surnames, those who know of a name change from one of the project surnames to the one they currently have, and those who match project members.
I have no problem with women (or men) who have one of the project surnames as their ancestral surname joining the Surname Project as long as they only have mtDNA and/or Family Finder tests. (if they have a yDNA test, I ask them to please leave the project, as their yDNA result confuses the Surname yDNA evaluations) I do not provide any coordination or reporting for mtDNA and Family Finder tests – though our project sites do provide a page for this purpose – should the admin want to use it.
I consider anyone with an ancestral surname that is included in the project to be a candidate for testing or sponsoring a representative of their family. Particularly because of this special relationship (but also because I try to be a nice guy), I try to be gentle and considerate with folks who shouldn’t be in the project
