Interesting topic . . .
In photography, contrast is important -- otherwise everything runs together. Same is true with typed text. All upper or lower case, paragraph separation, and punctuation give contrast to the written word and makes it easier to read. Early on as a programmer I designed subroutines that automatically convert whatever my users type to mixed case. So if they type, ROBerT JoNEs, it auto converts to Robert Jones when <enter> or tab is pressed. Data entered is available to printed reports so proper case is important to others reading those reports. Placing names or text on a report just as users enter that data would have ended my programming career many years ago. There would, of course, be exceptions. Though some do not use it, this forum has good spell checking available.
There will always be others that know more as to where our level of writing skills rank among others in the same arena - so I accept that and just do the best I can. When I wrote my first work to be published, my best friend, Fred, was my first line editor. He was an English Literature graduate from UC Davis. It was bad enough his red markings were numerous and bold, but if I was present at the time, he also enjoyed chuckling as he edited.
However, when the publishers editor then reviewed my work bleeding with red markings the reality of my writing skills level in the arena of published authors became apparent.
So hopefully everyone will continue to post and accept any suggestions by moderators and peers as a desire to communicate with everyone else on the forum. Would also suggest tempering suggestions vs. "rants" about the typing, spelling, or grammatical skills of others. Would hate to have that person with the knowledge to solve a problem I may have be reluctant to post because they had become paranoid about their data entry skill levels here.
