Welcome to Wikipedia. Everyone is welcome to contribute constructively to the encyclopedia. However, please do not add promotional material to articles or other Wikipedia pages, as you did to Woody Guthrie. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted. Take a look at the welcome page to learn more about Wikipedia. Thank you.

Please do not add promotional material to Wikipedia, as you did to Sewage treatment. While objective prose about beliefs, products or services is acceptable, Wikipedia is not intended to be a vehicle for soapboxing, advertising or promotion. Thank you. Velella Velella Talk 09:18, 2 March 2012 (UTC)
