I've exquisite knowledge of English spellings - not limited to North
American, but also covering British, East Asian, Australian, NZ, and South
African dialects.

Take heed, Sir, before making conclusions about who does what in real life
based on their postings on this little Microsoft Forum; you should be
acquainted with such individual beyind single0point contact medium such as
this forum.
SIR.

We're volunteers here, we don't get paid for wasting ime & health on helping
others.
Therefore I must type QUICKLY + often using a PORTABLE/MOBILE device, and as
you already suspect, let me using rough language:
I don't give 2 flying sh**s for spelling HERE.

To each his own. This forum is not a University, my boss, my wife, or
anything important.
For you it may be different as you either get paid or benefit otherwise from
being part of MVP program, or such.
For us - 95% participants here, making a typo/misspelling - however often,
does not translate into using this same "quickie go/post/done/run" mode. in
business communication.
SIR.
But thanks for keeping score of our typos - you should install a special
"typo counter" utility, so you sleep better knwing that country is secure
against vile mis-spelling bees.

Good night, SIR and may the Lord richly bless you and continue blessing
until you're thoroughly blessed.
SIR.
