That would all make sense if V6 was not still in beta. Yes, I do not feel this version is production-ready. I have had nothing but headaches using it. Maybe for simple D&D news, maybe it's OK.
So, for now, my client probably will use V5 to make simple news, and I'll use V6 so I can manage the bugs. I guess I'll know to import lists and users each time I send.
What about the unsubmissive? Will importing update these as well? God, I hope so.
