Hopefully this is the place for this kind of question.
This is what I want to do:
I want to add a note into a blog post, within the html that would not be visible to readers, but would reveal itself to anyone using html to read the article.
The note would be a warning that the article is copyright and unauthorized use is forbidden.
I was also considering adding into the note, a unique codeword so a search might find it if someone decided to cut and paste and claim it as their own.
Thanks if you can help with this.
