Assume that when an editor makes an edit, it was to help the wiki, not to vandalize it. Since anyone can edit, we must assume that most people who work on the wiki are trying to help it, not hurt it.
If you are positive someone made a non-constructive edit, then feel free to correct it. When disagreeing with people, remember that they are probably thinking they are helping the wiki. Consider using message walls to explain yourself and give others opportunity to do the same. This can avoid problems and prevent them from escalating.
When you see an unregistered user make an edit that you think may not be up to standards or is a stub, don't criticize them on it or delete what they put. You must assume that the edits were made in good faith. Think about what the editor's intentions were before judging them. Misspelled words or bad grammar are not to be considered vandalism; many editors are accustomed to writing short terms common on internet chat pages and areas of a similar nature. The good faith rule means that we do not assume they were trying to vandalize or create bad pages on purpose, but instead, they were attempting to contribute to the wiki and should be commended for the effort.
Be patient with newcomers. They may not know how to edit a wiki or what's supposed to be added as content.
What is not good faith
Actions inconsistent with good faith include constant vandalism and lying. If you have spotted obvious vandalism by any user, this rule does not apply. Vandalism can be reported immediately to administrators or you can revert the page yourself.
