AJAX Comments Refueled allows for pages to be cached without needing to invalidate on new comments, and is useful for upgrading the default comment system to not rely on page refreshes for replying to comments.
This plugin is a zero-dependency implementation. This means that it does not require jQuery.

Basic verification and asynchronous posting with snazzy effects. Developed specifically to work with the mootools framework.
Should deprecate peacefully, and tested in Safari, Opera, Firefox and IE7
MooTools is an ultra-light frame work with faster operation than prototype/scriptaculous and more intuitive nomenclature than jQuery. This plugin will not work if you already use another library on your site (JQuery, scriptaculous, etc).
