The YouTube Upload Widget allows you to easily add video to your WordPress blog.
This plugin is an answer to an WordPress site operator who has many different user accounts. This allows your users to record and upload videos from right in your WordPress site; you never have to leave.
It's really nice that you can upload a webcam video directly to youtube from within the WordPress Admin.
It's a pretty sweet setup. Easy to use, and you can not only browse existing videos and easily embed them, you can record from your webcam.
