Okay, I know this isn't going to be a popular response, but here it is.
I make mistakes, everyone does. I'm more than willing to laugh at my own mistakes and allow others to laugh with me, as a result I'm also willing to laugh with other's who mistakes. However, it should be in good nature and a lot of the responses on CF and other places on the web are not in good nature.
Comments about grammar and spelling being an indication of intelligence are wrong. Without a doubt my wife is smarter than me. She had close to a 4.0 in college and was on the dean's list when we met, but I'm a better speller.
People have strengths in different areas and posters need to realize that. Just because you can spell and they can't doesn't mean that you are smart and they are stupid. Undoubtedly that person could run circles around you in other areas. This is why there is more than one part to the college entrance exams.
If you feel so bad about yourself that you have to belittle other posters to make yourself feel better, then YOU have issues and need a wake up call. Laugh with others, not at others!
