Respect Others
It isn't possible to get far in the world if you refuse to respect others. Treat others kindly, don't insult them, and others will do the same in return. If you refuse to treat others well, then you will get not only a warning, but a bad reputation, which opens the door for more negativity.
No Spam
No one likes spam, it clutters the board, so don't contribute to the problem. Messages that do not contribute to the topic or forum are considered spam and the poster will receive a warning.
Use Constructive Criticism
When someone posts their art or other types of creation, they generally do not want it insulted or put down. If you do not like a work, post how you fell it could be better; Offer suggestions for improvement, but do not insult the creative works of others.
Keep it PG-13
This means no pornography, extreme violence, or even swearing. Attempts to bypass the censor will get you warned.
Read pinned topics and make sure to post in the right section
Pinned topics are there for the benefit of all. They save members from having to recreate the same common topics, and save mods the time of reviewing posts. Duplicate topics are a waste of both your time and the time of the moderation team, so any duplicate topic will be closed and their poster will receive a warning.
