A very useful and simple plug-in that allows you to hide a part of a post (links,image...) using standard HTML comment markers <!-- and -->. When WordPress converts your post text into HTML, one thing it does it converts a double-hyphen to an en-dash (– which in Unicode is –). This plug-in simply changed it back if it happens to be followed by a greater than symbol. Since --> is a HTML end-comment marker, this allows HTML comments to work again.
To hide a text,just place it between those two markers <!-- and -->. For example:
This is an example of a post with <!-- Hey, what are you looking at? --> hidden text.
