adCenterEU has updated us on the adCenter bulk import draft problem, saying at a WebmasterWorld thread that the problem will be resolved in a "month or so."
Microsoft will be adding new functionality to make it easier and quicker to import campaigns and mark those campaigns from the "draft" status to the live status.
adCenterEU, Microsoft's official adCenter representative, said:
Watch out for this capability in a release scheduled within the next month or so.
So I am expecting the release within the month of September.
