It would appear that if a member recognized a spelling mistake etc then s/he must have been able to recognize the word or intent for what it is (ie the posters intent)
Borrowing from a previous poster if a member keyboards "I prey"well a reader certainly understands the posters intent. The only opportunity to assist the poster without drawing attention to him/her is via a PM.
A public display is likely either because of ignorance or an intentional jab and again if not then please PM.
People retired and posting on this forum have accomplished much in their lives and should remind themselves that this isn't their first rodeo
