Want to run a simple website using WordPress Pages as a CMS, but don’t want (or need) the Post functionality? Want to do the same thing, but have Posts secondary to pages? This is the plugin for you. This plugin rewrites the Admin menu links for Write and Manage to default to using Pages instead of posts, while leaving the ability to deal with posts intact.
You can find more information (and the download) on the CMS-Like Admin Menu page.
