This component is a good idea. It is useful to me, as I needed a idea box component , 1.5 native.

To improve: The html is poor, you should use labels tags in the form and use w3c valid html. Also, why do you offer to the visitor to choose himself the date his comment is published, just use SQL's now() function.

Thanks a lot for your component, it's, as I said, very useful

Awesome plugin, very simple and natural to use. I thank its author a lot for that !! I didn't test it but you should use it with JACL+ (if you use J1.0+) to create custom user groups, or if you use J1.5+ I think you will have to customize in the core (see http://docs.joomla.org/Custom_user_groups)
