Simplify Comment Templates in WordPress 3.0 With the New Comments Tag
WordPress 3.0 has a new standard comment form tag that you should know about.
Whereas previously the code for outputting a comment form was much longer, now you have this:
<?php comment_form(); ?>
This will give you a simple comments form that looks something like this:
Now doesn’t that simplify your theme development?
If you want to further customize the comment_form template tag, I highly recommend OttoPress.com’s tutorial on the new form tag or check out the codex for more information.
