After 24hr (or sooner) from registration you will become a 'Registered Author'.
Becoming an 'Author' allows you to post content to the website, usually via a link in the 'Content' Menu. You can submit new content, select options to show the item on the front page and select dates for publishing and what class of user will be able to see it but you cannot directly publish any content. When content is submitted you will receive the message, “Thanks for your submission. Your submission will now be reviewed before being posted to the site.” You can edit only your own articles but only when that article has been published and is visible.
