The clone module allows users to make a copy of an existing item of site content (a node) and then edit that copy. The authorship is set to the current user, the menu and url aliases are reset, and the words "Clone of" are inserted into the title to remind you that you are not editing the original content.
This module is similar in purpose and function to the "Edit As New" module that was available for Drupal 4.5.
The ACL module, short for Access Control List, is an API for other modules to create lists of users and give them access to nodes. It has no UI of its own and will not do anything by itself; install this module only if some other module tells you to.
We're aware of the following modules using ACL (let us know if you know of others):
Flag is a flexible flagging system that is completely customizable by the administrator. Using this module, the site administrator can provide any number of flags for nodes, comments, or users. Some possibilities include bookmarks, marking important, friends, or flag as offensive. With extensive views integration, you can create custom lists of popular content or keep tabs on important content.
This module allows nodes to be published and unpublished on specified dates.
#D7CX This module got into core and will only be available as a back-port version for Drupal 6.
Provides vertical tabs like http://drupal.geek.nz/static/node-form/default/summaries2.html on the node add form.
This module provides the following features:
This module builds user profiles as content (aka nodes), which opens the opportunity to use all the powerful modules for content for user profiles too, e.g. the Content Construction Kit (CCK). It's intended to be simple and useful, but extensible by further modules.
Content profiles can be restricted to certain roles; the module also supports separate content profiles for different roles.
"auto_nodetitle" is a small and efficient module that allows hiding of the content title field in the form. To prevent empty content title fields one can configure it to generate the title by a given pattern.
When the token module is installed it's possible to use various node data for the
auto generated title - e.g. use the text of a CCK field (since 5.x).
#D7CX: I pledge that Embedded Media Field will have a full Drupal 7 release, and/or a migration to FileField (depending on the status of PHP Stream Wrappers + FileField in core) on the day that Drupal 7 is released. Views functionality will be available the day the Drupal 7 version of Views is released.
#D7CX: I pledge that Email Field will have a full Drupal 7 release on the day that Drupal 7 is released.
This module provides a CCK field type for email addresses.
The Content Template (a.k.a. ConTemplate) module allows modification of Drupal's teaser and body fields using administrator defined templates. These templates use PHP code and all of the node object variables are available for use in the template. An example node object is displayed and it is as simple as clicking on its properties to add them to the current template.
