jQuery Comment Preview is not so lightweight as the Live Comment Preview, but you can set the ID in options, so you don’t have to edit files. Q. I’m seeing two comment textareas with this plugin! A. Please check your template HTML and CSS for that element. Ideally it should use standard WP comment_form function and the same kind of CSS as the default template (TwentyTen). It needs to have id=”comment”. Q. All the comments go into trash! A. Same as above – make sure you use standard WP functions for display of comment forms. When you check out HTML source of your article page with comments bellow it, you should see two textareas – one with ID comment and the other with ID consisting of random numbers and letters. The first one should be set to invisible by this plugin.
