I'd like to clean up the End Users section of the How-to main page sooner rather than later and these are the changes I'm proposing.

The following are currently (mis-)listed in the End Users section. [ ]’s in bold indicate where I propose moving/keeping each item; [ ]’s in regular font are just additional notes/comments. Items not listed here are fine.

Installation and setup

Content space organization

NewsItems archive using SmartFolders and expirationdate
[Site Administrators] [possibly End Users as well but out of the box Plone doesn’t allow non-site managers to create SmartFolders; not sure if that’s still the case in Plone 3.0]

This howto shows a way to separate current news from archived ones using expiration date and smartfolders by making the catalog return expired items too.

Security and Workflows

Displaying only “published” items in folder listings to anonymous users.
[Site Administrators] [I’d also like to tag this document for refactoring or to be deleted if there are better docs that cover this topic – e.g. how to make a private plone site]

If you don't do this, Plone's folder listing option will display both visible and published items to anonymous users.

Sharing Editing Capabilities for Pages and Folders
[Site Administrators] [Also, this doc is missing all its pretty pictures; should be fixed or retracted/obsoleted]

This describes how to give a user of your site editing privileges of particular folders or pages.

General User Interface customization

Content components

Allow all inline styles in Kupu
[Site Administrators] [should probably be in Presentation Components instead?]
