Another plugin I am using on this site: Comment Validation by Jörn Zaefferer.

From Jörn’s site:

Why should you install it? Because you care for comments and want to help users reduce mistakes that hold them off from commenting at all.

Whats the technology used? jQuery and the jQuery Validation plugin with a few customizations to make it fit into the standard WordPress theme.

Is it compatible with other plugins? The plugin is tested with the Draw Comments plugin and works, though
