A lot of users maybe have noticed it, the submitted works don't appear correctly in the gallery, even if approved by a good response feed in your message inbox.
It's because the specific folders are not able to receive the works.
Internal problems of the submitting system, maybe bugs of the server, I sincerely don't know and I will send a message to the help center soon.
But, by the way, it's not impossible to submit the works.
It's just to submit into featured, the only folder able to receive the submitted works.
So you have just to select featured into the destination button in the submission window, then we will move it to the correct folder as soon as we can.
Hope it will help all the users that don't find their work, even if approved, into the gallery.
