I may make one jsut using jQuery another time.
Enjoy.
- Uses AJAX to submit comments
- Dynamically shows new comments
- Stores all content in database
- Dates and IP logging with the database
- Support for individual 'statuses' (each comment box is its seperate div, meaning no comment from one box will appear on another)
- Unfinished dynamic comment box
