I usually send the Plus Edition newsletter by email to all subscribers on Sunday evening, although I also add a disclaimer. I often state "...except when my travel schedule interferes" or some similar words. Tonight is one of those occasions.
I have to get up early in the morning to catch a plane from London, England to Orlando, Florida. I have decided to not stay up until 2 AM, as I often do, to compile and send the Plus Edition newsletter, especially since I have to get up at 5 AM. I'm going to get some sleep instead.
Tomorrow (Monday) evening may or may not be the same: while I should be in the Orlando suburbs by early evening, after eight hours in the air, crossing five timezones, I may have other things on my mind in place of sending email newsletters. Sleep might be a higher priority, especially if I don't get much sleep tonight.
The Plus Edition newsletter should appear in subscribers' mailboxes in the next day or two, after I am rested.
Thank you for your understanding.
