How many of you have deleted your own comment on another person's blog because you made a grammatical error or typo?
I do it all the time.
In fact, I just had to do it over at Tracy's blog. I made the dreaded "you're" "your" switch.
Here's a tip: Highlight your grammatically scarred comment and copy it. Then delete it by clicking the little trash can. Start a new comment, paste in the old one, make the change needed, and submit the fixed comment. Viola! You look educated.
