Here are some good resource I have found helpful in the time that I have been here. If you see something that is wrong or that I should add please leave a comment.

My mini Q/A: So many questions get asked on Newgrounds so many times just over and over again so I think the answers to these questions can't be in enough places. I'm not going to try to make a better FAQ then DnaDraxxus or cheekyvincent since I can't and I'm not going to waste my time trying but instead here are some of the more highly asked questions I see coming up a lot.

1.
Q: Is there a place where I can view how many whistle points you have and how many you have to flag before you go up or down a whistle?
A: No there isn't a location where you can view this. The whistle points system is a secret the just a few staff member know about, also there are rumors of how it works on the forums but these are just rumors.

2.
Q: I'm kind of new here and I still don't quite understand how the whole experience points thing works and I have already read the FAQ.
A: Everyday you vote on 5 submissions, you will receive 10 EXP points. Doing this often will give you more EXP points allowing you to level up and increase what your vote's worth. You can see a complete list of all the levels here.

3.
Q: When does the next Newgrounds day start so I can deposit my EXP points?
A: It starts at 12:00 am Eastern Standard Time.

4.
Q: How do I level up my whistle and what are the whistle levels?
A: To level up your whistle I would suggest that you read "Guide to get a deity whistle" by DnaDraxxus. Also the Whistle levels are Garbage, Normal, Bronze, Silver, Gold, and Deity.

5.
Q: How do I become a mod?
A: Well some good steps to take is to first not ask to become a mod, just be a model user and by that I mean you need to be helpful, act grown up, most likely have good stats, and get to know some of the other mods by helping them out and if a time comes where they need more mods you might become one.

6.
Q: How do you find the abusive reviews?
A: Well I often start by doing searches for things with offensive words in the title, or ill look for things that could piss people off in turn making that leave shitty reviews, or ill check the deposit ranks for people with real asshole type user names such as "fagsmasher90" or something else thats really crappy...
