[i]I've come across something called a DMCA that I think will get the company that runs the server of the website to take them down...[/i]

Quoted from http://www.dmcaattorney.com/AbouttheDMCA.php :

"We can help you if you are the owner of copyrighted materials that someone else is infringing over the internet."

Additionally: http://en.wikipedia.org/wiki/Dmca

"The Digital Millennium Copyright Act (DMCA) is a United States copyright law that implements two 1996 treaties of the World Intellectual Property Organization (WIPO). It criminalizes production and dissemination of technology, devices, or services intended to circumvent measures (commonly known as Digital Rights Management or DRM) that control access to copyrighted works and it also criminalizes the act of circumventing an access control, whether or not there is actual infringement of copyright itself. In addition, the DMCA heightens the penalties for copyright infringement on the Internet."

The DMCA does not apply in this case. Your screen name, "God's Warrior" is not copyrighted, nor are your posts. Yahoo's Terms of Service has this to say:

http://info.yahoo.com/legal/us/yahoo/utos/

"With respect to Content other than photos, graphics, audio or video you submit or make available for inclusion on publicly accessible areas of the Yahoo! Services other than Yahoo! Groups, the perpetual, irrevocable and fully sublicensable license to use, distribute, reproduce, modify, adapt, publish, translate, publicly perform and publicly display such Content (in whole or in part) and to incorporate such Content into other works in any format or medium now known or later developed."

"Publicly accessible" is defined in the following way in the Terms of Service:

""Publicly accessible" areas of the Yahoo! Services are those areas of the Yahoo! network of properties that are intended by Yahoo! to be available to the general public. By way of example, publicly accessible areas of the Yahoo! Services would include Yahoo! Message Boards and portions of Yahoo! Groups and Flickr that are open to both members and visitors."

Concerning your implied claim that material you have submitted to Yahoo! Answers is copyrighted I quote once again the Yahoo! Terms of Service:

http://info.yahoo.com/legal/us/yahoo/utos/

"CONTRIBUTIONS TO YAHOO!

By submitting ideas, suggestions, documents, and/or proposals ("Contributions") to Yahoo! through its suggestion or feedback webpages, you acknowledge and agree that: (a) your Contributions do not contain confidential or proprietary information..."

But by all means, feel free to waste your time and money pursuing this nuisance suit. The best news I can give you is that most attorneys provide an initial consultation free of charge.
