Rules of Engagement
In addition to these guidelines, note that this is an entirely strategy driven wiki. Whilst articles may include a brief introduction regarding the character's history, the wiki is not a house for canon discussion.
Don't scribble all over someone's page. The Wiki has built-in tools to help authors protect their content. Don't make their job harder by trashing up the place. A wiki is most useful when it's open to the entire community to edit and refine its knowledge. Right now it's completely open, but we will start moderating it if things get too out of control.
Don't Create Blank Pages
If you don't have the knowledge and the intention to add the content to the page then do not create the page or the section within the page. The wiki is not a place to request information. Also do not create a whole series of pages unless you have the time to complete the content in the pages. Exceptions are only for the administrators when a new game is released and the section for the game is being created from scratch.
Maintain a Consistent Style
We've filled in a basic skeleton for the way things should look for most sections. Check out the section on Marvel vs Capcom 3 for an example of how the front page for a strategy section should look, and Dr. Doom's page for an example of how a character's page should look. However, certain details should obviously be omitted as necessary. We implore you to provide new content for the wiki, but ensure your contributions are in an appropriate format.
Record your Progression
Get into the habit of marking out links to article with the appropriate image affixed to the end relative to it's completion rank. It should go without saying but, 0% refers to a completely blank, or only very loosely outlined article, whereas 100% refers to a completed article.
If you think there is only something very minute that you are, for whatever reason, unable to rectify limiting it's completion, please additionally attach an asterisk (*) to the 100% progress .gif and the note in italics at the end of the link.
e.g. * Capcom Fighting Evolution - Missing one of the characters from the tier listing entirely
Note that these should only be used to describe the destination article ONLY. All child links are subject to separate scrutiny.
If you've never used a wiki before, the MediaWiki User's Guide contains lots of information for usage and configuration help.
If you'd like to jump right in, editing a Wiki is lot like writing a forum post, except the markup rules are much more rich. You can check the Editing section on MediaWiki for a description of all the rules available, with some brief examples.
