yeah, its kinda complicated.
you dont have to put them in folders if you dont want to,
and you dont have to sell prints if you dont want to
(but if you do, after you submit the diviation it should take you to a page about it, although I always click off of it cuz I dont really sell prints)
and to upload stuff its in the middle of the top where it says "submit "
I always have a hard time finding it. lol XD
