This error occurs due to the fact that series creation is disabled only for authors who have not yet had a story approved by our staff.
As a new member, you may find that some options are not available to you, such as series creation. This is because we do not auto-validate our members for author-level access until they've submitted a story and had it approved by the staff. After your validation, you can submit and create new stories or series at your leisure, without the need for staff approval.
Be sure to read our submission rules before submitting.
