Look on the left hand side column and click on "Forum." The forum is moderated by the host (who wrote the article.) Her name is Jessica Steinhoff. About.com is widely read. It may not be a bad idea to take Steinhoff to task over that highly inflammatory tip sheet.
Another good idea is to notify "Customer Care" of About.com.
