What are some pr submission sites that are free to use?

It doesn't cost anything to register for the sites, but I want a few sites where on earth I can submit a press release for free. Any assistance would be great.

Answers:
While outfits charge as much as $650 per release, in that are free press release submission places on the Web. Press releases allow you to (a) attract medium attention; (b) win more support links to your website minus sending respectively website an email request; and (c) win more visibility especially if your press release get contained by G00GLE News or Yahoo News.
