Press Release/News Sites
This is a growing list of websites where you can post press releases and links about your game products and information. I've tried to list the basic requirements for posting, as some will require you to have a user account to submit any information or allow your press release to formatted in a specific way (html, ubb, text). If you know of some resources that are not listed, feel free to send an email with the information.
