SmashWiki:Read This First, Man
[insert cheesy introduction here]
Step 1: Get the point
While you should know this by now, we are a wiki. We're not a forum, or a personal webspace provider, or a social site, or a strategy guide. We are an organized encyclopedic collection of information that depends on its userbase to provide correct and up-to-date content. To that end, we expect all users to have a reasonable work-to-fun ratio - you are allowed a certain amount of freedom on user pages and forums, but at some point you will be expected to contribute positively to the wiki's goal.
Step 2: Get the rules
As a new user, you are not required to know the full technical ins-and-outs of every policy and guideline; other users will generally assume good faith should you break rules, and administrators will almost never issue blocks without outlining what you have done wrong. Regardless, it is your job to be aware of the rules and how they apply to you; ignorance of rules is essentially never accepted as a valid excuse.
Step 3: Lurk
You may already know this, but all wikis have a special page called Recent Changes used to keep track of all edits made to the wiki. [fill this out a bit more]
