Ultimate Tag Warrior is a way to add tagging to your blog posts. It will give you a chance for users to easily bookmark your blog posts through such social networks including del.icio.us, Flickr, and Technorati.

Unfortunately, it is difficult to install as I had installed it and had problems getting it working. I probably could have figure it out, but I was only installing it to get another plugin to work because it was required.

You can download the wordpress plugin from the original source here

If you need support with it, you can go to their official forum
