1.  Keep your post nice and tidy. Nothing  is more off putting than a badly made post. This can be caused by simply copy and pasting from another website and failing to edit it to make it look nice.
2. No Cracked servers. World of Minecraft does not promote illegal activites.
3. Keep it to one thread per server. Do not make more than one thread for a single server.
4. Be respectful.

Breaking any of these rules will probably end up with your thread being deleted. With or without warning.

That is All :)
