Share 'Wiki help'

I've done a wiki before, but I'm just now starting a project where I want an effectice wiki. Being fairly anal-retentive about things that aren't uber-important, I need to know: how do I stop the automatic alphabetization of the page listings? I want the book studies in one section, and the other widgets and so on separated from the book studies, not mixed in. Does anybody know? Has anyone care…
