This is a flexible module that provides a userfriendly wizard for creating and editing several nodes.
The module can be used to provide a user friendly wizard for creating and editing several nodes. You can use the module to create a "route" which leads users through multiple pages, which can be e.g. a node creation form or a node display.
The basic email field type is in core now: #1668332: Add an E-mail field type into core, making this contrib module obsolete. Specific formatters (like the contact form) can live in separate contrib modules.
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.
Computed Field is a very powerful field module that lets you add a custom "computed fields" to your content types. These computed fields are populated with values that you define in PHP code. You may draw on anything available to Drupal, including other fields, the current user, database tables, you name it. (Feeling the power yet? :) ) This field is literally the Swiss Army knife of fields. So start cooking up your PHP based values!
