SmashWiki is an English wiki. Simply put, SmashWiki expects all participants to have a functional understanding of English and be capable of reasonably expressing themselves in English.
This policy is intended to be simple - understand English, and use correct English. It is assumed of all users that they are capable of understanding and using correct English. No special considerations will be provided to any user who demonstrates otherwise.
In short: If you can't understand this page, you probably shouldn't be here.
