Duosuma: Request an Account What is Duosuma? Duosuma is Duotrope's Submission Manager. It helps publishers and agents receive and manage their submissions quickly, easily, and affordably. Learn more. Publisher: Twelve House BooksNote: A single Duosuma account can include multiple projects, so we recommend creating an account for the top-level project, rather than an individual publication. If that doesn't work for your organization, please contact us to discuss your needs. Authorization: I am the owner of Twelve House Books and am authorized to request this account. Important Note: The person who creates the account is designated as the account's "owner" and will have complete administrative control over it. The owner is legally and financially responsible for the account. Also, the "account owner" role should not be given to a short-term member of the staff (such as a student editor). Please make sure the appropriate person makes the request. Your Full Name: Note: This must be your full legal name, not the title of the project or a job title such as "Administrator." Your Email: Note: For your security, we will email the address we have on record for The 13 Days of Christmas Anthology.Please provide an address below in case we have trouble contacting you at the address on record.
