Well, here\'s a slightly edited one taken from another forum. I guess they\'re all basically the same, so you could just add/delete things from this and change a few details to speed up the process. I\'ve already read through and altered it for use in our forum.
Think there\'s anything missing? I didn\'t write any of these myself and I\'m useless at being thorough.

[Edited: I wrote #9. The original post didn\'t have a signature rule and that was the most important thing!]
------------------------------------------------------------------------
Code of Conduct Remember that there are people behind all the nicknames. Act towards them as if they were to knock on your door the next moment. Be respectful, kind, positive and polite. --------------------------------------------------------------------------------
A post is your nickname, the subject of the post, the main text of the post, your personal location and the signature of your post. --------------------------------------------------------------------------------
1. Foul Language is not allowed. This includes any word that is considered degrading to the person or thing it is describing, any profane word or any combination of characters that will give immediate associations with such a word. (e.g. fok, f**k, fuk)
2. Do not Flame. Flame, a post that has within it the purpose of personally insulting or putting down a person or idea. This includes the unfair treatment of newbies, i.e. insulting or degrading new players purely because they have not been around or played as long as you have.
3. No Out of Context posts. A post is out of context when it is not in accordance with the topic of the thread, or doesn\'t respond to other posts, or continue the ongoing discussion, in the thread.
4. Racist, Religious or Sexual Offense is strictly prohibited. Any degrading remark concerning any one person\'s race, religion, nationality, gender or sexual preference or ability, or that in general, is strictly prohibited.
Older forum members should remember their position and not use age as an issue to offend younger posters.
5. Pornographic content. Any pornographic content, or referenece to a site with pornographic content is prohibited.
6. Spam. A number of posts that do not violate any of the above rules, but that do not have any content whatsoever is considered spam and will be deleted. It is also spam when the same post is posted a number of times or when the message has no purpose or meaning.
7. Language. All posts in this Forum should be in English, or with an English translation of the text in a foreign language.
The only exceptions to this will be if there is a moderator fluent in the language of the thread who is willing to take on the responsibility of moderating it.
8. All thread-titles should describe the intended discussion in the thread as well as possible. Any thread title which is in violation of any of the above stated rules may be deleted or the thread title changed by a moderator.
9. Signatures. No signature should be in violation of the rules stated here. The size of signatures should not exceed 500x150 pixels. Animated signatures should not be over 200kb in size as this will decrease the performance of the forum and cause slow page loading.
10. A discussion in a thread between two posters that is of no interest to the community is to be conducted by other means of communication, such as using the forum\'s Private Message function or external means such as email.
