Citing sources : Could use additional citations. These could be from Baird's manual, or a notable publication or book, a university yearbook or official university portal for the student organization.
Wikify : Generally this is a solid article. The lede paragraph is too long, and its detail ought to be moved to the History section (Intros should draw people in, not attempt to answer all their questions.) The chapter list should be placed into a table format, like this: Sigma Delta Rho as an example of a small page list, or like List of Delta Kappa Epsilon chapters when placed on a separate page (to reference two unrelated examples). 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 school portal pages, and allow comments on where a chapter came from, interesting facts or its outcome.
Talk pages are where people discuss how to make content on Wikipedia the best that it can be. You can use this page to start a discussion with others about how to improve the "Sigma Psi Zeta/to do" page.
