Do you have a question about Newgrounds? Is there not a guide available as of now that can answer your question?
Post it here and I will answer it! Avoid sending PMs though, for one it taxes my storage space, and two chances are someone will ask a similar question, and if it's in this post they can see it and get their question answered.
However, if there is a guide available to help you answer the question (for example you have a review deleted and the abusive review guide is posted), use that first, and then comment on the CORRECT guide post if you still have any questions.
Think of this as the Wi/Ht? forum, except the BBS rules don't apply here.
