Infobox : The infobox may be incomplete. The template used for this entry, where you can see all available fields (--these things: "| = text") is the fraternity-specific infobox. This, and other useful items are linked on the Fraternities and Sororities Project page.
Maintain : Set a calendar reminder to update the chapter list, member count and otherwise check the article for necessary updates, annually.
Update : If calling out specific chapters in the body text, italicize the name of the chapter. Wikipedia practice within the F&S Project is that the word "chapter" is not capitalized, while the name of the chapter is. After reviewing it I deleted the Controversies section which had been too detailed for a main article, and unfairly frames the entire national as if the event was systemic; notes about an individual chapter's closure or suspension ought to be rendered as a reference note for that particular chapter unless the event generated notable, persistent national news. See Talk page discussion.
Wikify : Confirm the physical address annually and occasionally confirm the websites. Occasionally, update the number of chapters and number of lifetime members. The Fraternity's and the Society's chapter lists should be placed into a separate table format, like this: Omega Tau Sigma or Sigma Delta Rho (to reference two unrelated examples), or as a separate standalone page when the list is lengthy (subjective, perhaps 30 chapters or more). Indicate what is meant by "Affiliated groups". A chapter list should include dates of chartering. Indicate if a chapter is active by bolding its name, or if inactive by using italics. A table will allow room where chapter references may point to portal pages, and allow comments on where a chapter came from, interesting facts or its outcome. A table may also be used to showcase notable members, but be sure to add Inclusion Rules to avoid vanity listings.
