I don't know what this person's situation is. However there are many times I will leave this site to go to a dictionary site to check my spelling or how to make a plural out of a word. For instance, yesterday I had no idea if you use a plural for penumbra. I still don't know. And, of course, I check other sources to see if I have my facts right. But I know that unfortunately that really doesn't matter any more. Finally, I often go back days later and realize that after being as careful as I can be I still have misspelled words. I try to edit things so that I do not look too stupid. By the way, do people not pay attention to the auto-correct function that comes up on computers or do you have to do something to be able to use it?
