Making sure you view the latest and greatest Aug 23, 2018

In working through the tweak of "Invitation to Participate" I experienced browser aggressive caching preventing me from seeing the change.  I am using Chrome on Mac.  I actually had to quit Chrome and restart and then all was fine.  Simple page refresh didn't cut it.  The latest and greatest will have a date stamp of Aug 23, 2018 in the lower right corner of each page.
