For knowing what are you allowed and what you aren't allowed to post here, I recommend you to take a look to the Content Submission Guidelines (which you can consult here, right at the following link below):
(https://www.newgrounds.com/wiki/help-information/content-submission)
You can also contact via PM with a Moderator, or else using the "Where is/How to/Help!" section of the BBS for asking, but I would recommend you to do this on specific cases (when it's really necessary and the Content Submission Guidelines aren't enough intuitive).
I hope this was the response you were looking for - have a good day.
