Mambot that allows you to insert comments in your content articles/items with your wysiwyg editor that will not be seen on the public/registered website. Totally mambot and PHP code no Javascript. This is not a commenting system for public viewing like most of the other commenting solutions, this is for your eyes only when editing content. Fully documented in the mambot. Many uses-from helping users with html code to brain storming an article for later write-up. This an alpha release because I have not tested it with all language sets and UTF-8. Please report problems over at my forge page Enjoy
