javascript character counting in a form

Hi -

I've seen a few websites that show you how many characters you have
left while you're typing. Does anyone know of a plugin to accomplish
automatically?

Thanks,
Dino

I found this plugin:

http://text-area-with-status.googlecode.com/svn/tags/text_area_with_status

by searching for "characters left" I hope it works out, I'll post
back.
