Some folks who have subscribed to the RV Builder's Hotline say they have not been getting it. I got very few bouncebacks this weekend.
Update It looks there was a problem with the Dada Mail program I was running. It was reported having sent them out -- and, indeed, some people did get them -- but I wasn't being notified when they bounced back or weren't accepted by your email client. So I've sent them out again on the other program I was using to mail them out (the one I was using on July 12 -- the last time people reported getting them en masse).
My apologies. In the meantime, PLEASE make sure email@example.com and firstname.lastname@example.org are both in your address book.
