Wanna say something about the page without necessarily adding any content to it?

ADD A COMMENT BOX!

Gimme a [[Comments]]. Whalahh, you're ready to comment.

You can also chose an alternative text by doing this: [[Comments(Hey dude, leave a comment!)]].

Note: Make sure it's at the very bottom of the page, because when you enter text into the comment box it will simply append it to the very bottom of the page. It's exactly the same as making a usual edit of the page, except the time and your user name will be appended for you. How awesome is that! Comments are limited to 1000 characters, so if you have something long to write it may be better to edit the page directly.

When to use a comments box

I think comments boxes work well on pages where the comments aren't likely to be integrated into the 'normal' page content. Experiences/personal opinion is good for comments. I think comment boxes are harmful when people use them to actually contribute to a page. Then you're left with a mess of a page that always has to be refactored. A good rule might be: if you're finding yourself replying back and forth using a comment box then it's probably best just to edit the page itself
