Use {wtwcomment}For my eyes only{/wtwcomment} and it will not be shown on your website. Leave yourself a comment in your article/item for later ease of use.
Mambot for Joomla 1.0.x 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 is now a beta release.
I use this as a publisher to leave code snippets and help on use of mambots for registered users who may not be able to use joomla to its full advantage
Enjoy Ray
