Unless he did it through PM, he has not. He has not, in fact, posted a thing since he came here and asked for help. I don't blame him, and it would not surprise me if he never posted again.
The thread was originally posted in one of the new diver forums that is supposed to be a green zone, a place where new divers can come and ask questions, any questions at all, without fear of ridicule. He asked a question and was immediately blasted for his spelling difficulties. Even after the worst posts were removed, later posters continued to mock him with deliberate misspellings.
In my career as an English teacher, I had a number of students with genuine learning disabilities who simply were incapable of spelling. I know there are scoffers who will talk about laziness, but I assure you there are people for whom the letters are simply jumbled for them when they try to read or write.
Some of them are extremely intelligent people. In one case, a student enrolled in an online program at the 12th grade level in a chaotic beginning of the year scenario. He quickly distinguished himself at the top of his 12th grade English class--until his IEP came in revealing he both read and wrote at a 2nd grade level. Investigation revealed that he was able to read the challenging material in the class using a screen reading software program, and he was able to write his excellent essays through a screen writing program. When the material was read to him, he could understand college-level material with ease. When he spoke into a microphone, he could create college-level essays with ease. However, he could not look at a page of written material and make sense of it, and he could not write anything on his own--almost completely because of spelling problems--that anyone could understand. Until he took the 12th grade class and hid his disability, everyone had assumed he was incapable of that level of work because of his inability to spell. This was the first class in which anyone had assigned him any work above the 2nd grade level, so no one ever knew that his ability to read and write was actually at the gifted level.
So, if you feel the urge to mock people with such disabilities again, please think twice about it. Your mocking post will not be the first time it has happened, and the poster will be quite stung by it. If hurting people is your goal, you will have achieved it. Nothing else will be accomplished, though.
