Try not to attack others.
It's easy to sling personal attacks at others. Simple
disagreements can easily turn ugly once the insults come
out. Realize that it's almost impossible to change
someone's mind over the internet. Don't start attacking
others. Personal attacks will get you banned.
Don't spam the comments.
Nobody likes repeated posts, page widening posts. Being
annoying to everyone will only get you banned.
Use only one account.
Do not register more than one account to spam the comments
or other such things. One account per user.
