Willie, I actually didn’t see the “EVDL Administrator” questions. I don’t see his stuff - they go automatically in the bit bucket.
As far as the main question you and Peter posted, I’ve posted that I prefer to sit back and see what others come up with. I’m pretty sure I’ve already posted my thought on it in the past. I may do so again, but I’ve waiting to see what others could come up with. - Mark Sent from my Fuel Cell powered iPhone > On Aug 23, 2021, at 5:52 AM, Willie via EV <ev@lists.evdl.org> wrote: > > >> On 8/23/21 6:09 AM, EVDL Administrator via EV wrote: >> Mark, I'd still like to read YOUR responses to the questions posted here, >> especially to my own questions. > Ditto.
