 * Have at least 500 edits, a majority in the main namespace not blog or talk page comments. (see Special:Editcount, User contributions)
 * Be an active member of the community.
 * Follow and work to implement the Wiki policies, including Vandalism Policy and the Manual of Style.
 * Contribute to articles using correct grammar, spelling, and punctuation.
 * Understand the difference between vandalism and bad faith edits.
 * Demonstrate patience with new users and be willing to help point them in the right direction.
 * Be active in the community: communicate with other users through talk pages, IRC, email and/or vote frequently.
