13YO is in school and goes over spelling. Once out of HS... you have no such training. My boys can do high-end math way better than me at this time. Give them 20... and their children will school them as they forget by not using the skill. Not surprising. As Alex Baldwin says... "Spelling is a class? I thought is was an app."
Sometimes spoken words and thoughts don't translate well into forum text for some folks. As long as they can get the point across, typos should be forgiven.
I wish I could post some of the management memos I have seen, and still see. They look like a 5th grader wrote them. Pretty hard to respect someone who can't even write a correct sentence, much less a paragraph. Fred gets what he pays for with management too.
