Visitors to your site are forced to preview their comment prior to submitting it.
The plugin works like TextPattern's built-in "force comment preview" feature by forcing your commenters to preview their comments prior to submission. In addition this plugin is AJAX enabled so the user does not have to reload the page to preview his/her comment. Here are the key benefits of having this plugin enabled.
Comments quality will increase as users will be forced to preview his/her comment before submitting it. Previewed comments are sent through WordPress' various filters so that the user can see exactly how his/her comment will appear after it is submitted.
