I hereby declare MobileMe completely and utterly broken in terms of support processes.
Not only have I not received any acknowledgement of my issues since last Thursday the 10th, support chat is gone, e-mail support quotes a 48h response time, and I have not even received the acknowledgment e-mail this page mentions.
If anyone knows how to get hold of an actual live human being on the phone, drop me a line by e-mail. Or tip off Steve for me.
Or (even better) make me an offer I can’t refuse regarding switching to a better overall solution, before I feel tempted to build (or help build) one myself (and yeah, I just might).
