If a thing isn't worth getting the technique to say, it is of inferior value.
Many sites provide information on the art, craft, and business of writing.
Resources are available whether you write poetry, novels, short stories, drama, screenplays, or children's literature. Scam artists have preyed on unsuspecting offline writers for years. Online, the situation is only going to get worse because, as you know, scams flourish in the anonymity of cyberspace. You may save yourself some money by reading the Writer's Center Test Kit for scams, available in the site's Resources section. The Writer's Center is hosted by a Bethesda, Maryland, workshop that covers all genres, including poetry, short and long fiction, drama, screen, biography, feature articles, non-fiction, and business writing.
