I do appreciated the reminder. It's just I'm not use to anyone who cared so much before. You use humor to soften the correction which is nice and kind words as well. But many at curezone are cynical due to heavy debates, forum wars, and putting up with down right strange behavior in people. They may have a tendency to not see it as you intend. Many times sick people's humor tend to run a little thin and they do not appreciate someone making them feel like there is one more thing they need to work on. Most feel a little overwhelmed already. So if proofreading comes easy to you but not to them, they are liable to not be happy that you mentioned it. Just a health/safety hint that I learned being here at curezone.
But all in all, I'm sure it would be good for people to clean up their writings. Even though we may be lazy, we should remember that through the years, many people will read these posts. So it's much like writing a book, other than we don't own the rights to it. So we should take some pride, even if we are anonymous.
