Sometimes things that seem like spelling errors are just typing errors. I do not always use spell check when I am rushed. So do not worry. But even so a poor speller could be a great physician. Spelling is not everything and some people are just bad at it just like some can not do math well. Different strokes for different folks. Now grammer is not my thing. Had poor teachers all they way through. Plus they changed to New English and this and that every 2 years.
Congratulations! Not one typo or spelling error!
That is a good “about page.” :)
