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.
