PmWiki has the capability to stage ''draft'' versions of a page prior to them becoming "official".  Multiple interim edits to a page can be temporarily saved in a "-Draft" copy of a page until the draft is ready to be published to the original.

When the site administrator sets $EnableDrafts in a local customization file, the "Save" button on the edit page is split into separate "Publish" and "Save draft" buttons.  

The "Save draft" button causes any edits to be saved to a "-Draft" copy of the original page, leaving the original page intact.  Subsequent requests to edit the page (either the original or -Draft) bring up the draft copy for further editing.

The "Publish" button saves back to the original non-Draft copy of the page, removing any -Draft page that may have been created.

By default, saving drafts and publishing are available to anyone with 'edit' permissions (see [[Passwords]]).  However, the site administrator can also set the $EnablePublishAttr configuration variable, which provides a separate 'publish' permission that is required to publish to the original page.

Q:  How do I moderate all postings?

A:  Start by [[Drafts | enabling drafts]] to change the "Save" button into separate "Publish" and "Save draft" buttons.  Then set $EnablePublishAttr.  This adds a "publish" authorization level to distinguish editing of page drafts from publishing.
