Circle43's USCG boats
I also have suggested he refrains. Unfortunately he has chosen to continue so we will have to hope he alters his choice.
I attended a course on written communication many years ago and received book "The Plain English Story" ISBN 0-907424-01-5 by Martin Cutts and Chrissie Maher. This identified many cases of all capitals in insurance Documents (etc) in small type. Also formed the basis for the format of most of our Govt documentation to this day.
Age has nothing to do with the ability to read a document. Our brain follows the pattern of the letters and recognises a Capital as a name/place/etc or as a new sentence. Speed readers are able to use this to good effect. Two or more capitals act similar to a red traffic light and stop the reading flow and make us read each letter.
Live long and prosper
