@Montana Could at least an official announcement be published at the forum that would act as the central point of reference for the process? It would reiterate the key bullet points and link to the blog post, the documentation, the common observed problems, stress the need to migrate to .com (if I understood correctly, you are NOT migrating projects automatically, users need to do this themselves) and caveats associated with this process.
It would also really help to then broadcast the link to that post via the Web UI. I really have no idea why you are not using it. If there’s some technical problem or something, perhaps I can help?
I guess better late than never, you will at least somewhat save face! Being so sneaky and secretive about a major breaking change of both technical setup and TOS gives you REALLY bad publicity!
