Bruce is correct.? My group name has an underscore as we followed the same name as the YG before transferring over 1 year ago.? Now in order to create a subgroup I would have to rename the group and take out the
underscore.
Does the automated transfer process have a way to translate underscores in the name to something else?
You have to create the new group before you can initiate a transfer, so this issue with acceptable characters should be encountered upon group creation and has no bearing on the transfer agent.
I suspect the underscore restriction has something to do with the subdomain addressing that one encounters in groups.io when creating subgroups. Y!G has no subgroups.
