Extension:TalkBelow

The TalkBelow extension shows the talk page below the content. It also includes a friendly form to add new topics and handy reply buttons similar to those of Extension:DiscussionTools to reply to comments without having to visit or edit the talk page.

Usage
TalkBelow is designed to work out of the box and has no configuration options.

If you want to disable it for a particular page, simply add the  magic word anywhere in the page. If you want to disable it for a group of pages, the easiest way is to add the magic word to a template shared by all those pages.

Note that this extension adds no styling to the talk section it creates. However, it wraps everything with convenient CSS classes so you can easily style it to your liking from MediaWiki:Common.css or similar.
