I've also wanted to do this for the last 18 months.
Since gmail on the web provides a built-in RSS feed, it would seem that we should only need to add the user/password login switch to the URL when creating an RSS feed favorite in CarWings. But it appears the CW RSS reader client doesn't support this basic capability.
Surely the talent we have circulating on MNL can come up with a clever workaround for this??
Back when I first got my 2011 Leaf, I ran the issue past 800-NOGASEV customer service, but should have written a message in a bottle and dropped it down a well, for all the help they offered...
Wouldn't this be a very desirable feature to have for any LEAFers with a gmail account (or Yahoo or hotmail, etc.)? I'm sure this can be done by one of the tech wizards on this forum. Anybody???
