You have to email them.
Indeed, thanks. I did that after posting, thinking it was a logical thing to do, and as you said, Tesla responded in a matter of hours. I'm 550 of 6000 and they also said they have no news more current than the May email update. I'm not sure I can part with my cardboard box, bandaid box (perfect size for a J-1772 adapter) and my kleenex box that reside in the center section though. After 22,000 miles they are like old friends. And I must add, the TMC forums are a wealth of valuable information.
