Allow to display comment form inside post, page and widget.
Basically comment is inbuilt feature in WordPress but in some case we need embedded comment form.
Example.
* we need to embedded comment inside post.
* some theme build without comment form for pages or custom post type.
* you want to display comment form for specific post only, so you can disable comment for all page and use shortcode to display comment.
* in custom development you need comment form inside widget.
so here we have comment form shortcode to display comment using shortcode inside post,page or widget.

You can use below ShortCode in post or page or in widget to show comment form.
[comment comment_file =”/comments.php”]
Here comment_file is optional, if you have custom comment file, you have to pass here.

This is the first <a href="http://www.nabaztag.com" rel="nofollow ugc">Nabaztag</a> API plugin for WordPress. With this plugin every time a user will leave a comment (not moderated by Akismet as spam) the bunny will notify via Text-to-Speach API.
Actually the plugin will only send text message, but in the future I’ll work on ears and light support too.
Please note that the plugin is in very alpha stage and need PHP_CURL to work.
The <a href="http://svn.wp-plugins.org/fcc-nabaztag/trunk/Changelog.txt" rel="nofollow ugc">changelog</a> is a good place to start if you want to know what has changed since you last downloaded the plugin.
