I got a couple of Rules for the Art Forum:
1. Dont be a complete Antagonist, dont only focus on the negative aspects of a piece, you can point out flaws but dont be like "this, and this, and this, is all wrong good job, ******** up." When you are giving comment on a piece try to give come constructive criticism.
2. If you have knowledge on how to do something or know somewhere someone can learn tell them or give them a link. For example if someone posts a Signature they made and you know of a tutorial they could use to perfect a certain style then link them.

Dont just post your art work, also link us to good tutorials, or art resources.
