Hi Cal,
I had 8 medium-sized Yahoo groups and didn't want to pay 8 x $110, so merged these groups into one super-group and then transferred this to Groups.io last weekend. Groups.io allow the formation of sub-groups, so I am now sub-dividing my super-group into 8 sub-groups. Of course I needed to merge the membership lists for transfer and put all my files into separate folders. I transferred over 350 files this way and now want to find a way of moving the folders down to the sub-groups.There is a Move icon but it doesn't address sub-groups in Main.
Any advice welcome.
