Also, not providing any status results from the Stage 1&2 download, and then only providing the current wording for your Stage 3, seemed a bit vague & uncertain to me -- at least until I started reading support clarifying questions and reassuring replies here. The queue seems to move slow, and I just wanted to make absolutely sure a transfer would complete before the Dec 14th deadline, and that it wasn't dependent on my position in the "queue", which isn't moving very fast at this point.
To help clarify/summarize the current state of the transfer, especially for new customers here, could you please enhance the wording for Stage 3 to something like this?...
