I'm very happy to report that it now works -- now that I've got Mail working to receive on the iPod. Thanks! So far so good.

I'm not happy about having to use Mail on the Mac itself to send it. (It fusses with the system here in little bad ways.) It occurred to me that if the problem is with receiving the link-message in a browser, maybe I could send from browser-based mail on the Mac. But now when I try that (through Google Notifier, the only option besides Mal for a default mail reader), I get an error message: "Request-URI Too Large -- The requested URL /accounts/TokenAuth... is too large to process."

Anyone know a way around that?
