It wasn't your fault because that is how it was in the article you cut and pasted. You might have noticed it and deleted the repeated copy, but most FReepers don't. It's NBD.
THANK YOU! I didn’t notice! I remember when it was common to wander an article and pick out bits and pieces, but something changed with the “excerpt” rule and now I just grab near the beginning and hope it’s under a hundred characters. I’ll try to be more careful. Thanks for your careful explanation.
