Do persons have to be members of the groups.io main group before their Yahoo group membership can be transferred from the Yahoo group into the groups.io sub-group?
I hope I asked this right. As:
Yahoo group?????????????????? Groups-io group???????????? Groups.io sub-group
Bill Smith???????????????????????? Bill Smith???????????????????????? Bill Smith???????????????????????????????? Would transfer correctly (though NoMail perhaps in main group)
Jim Jones??????????????????????????????????????????????????????????? ?? Jim Jones??????????????????????????? ? ?? Would not transfer correctly
