DA is pretty intuitive. Time will show you how it's easy. ;3
Well; first - and most important - of all: aim the "Submit" link at the top of the page and then click in "Submit Art" to send a drawing, photo, poetry, etc. of yours. Share your art with the world!
You can aim the DeviantArt logo's down arrow at the top-left corner and then click in "Help & FAQ" to get more info.
You could ask some closer friends for more detailed info, too. Don't you know anyone who also has a dA account?
