This plugin will display a small ??? icon that links to either the definition or the translation of the word. The plugin is a no-brainer to use: [define:dog] will define the word ?dog? and [en2fr:dog] will translate the word ?dog? from english to french. [wikies:dog] will show the Wikipedia article for the given word in spanish (es). Dictionary.com is used to define words, as it has definitions for technical terms too. Translation works with Google’s translation engine.

This plugin creates new user role called “Web Administrator”. This role has more permissions than Editor or Contributor roles but less permissions than Administrator role. Therefore, this role is perfect for users who should not have access to critical functionality (update, manage plugins, manage themes, etc.) but still need access to some advanced options.

Web Administrator User Role

Plugin that automatically creates custom role for Web Administrators and allows to edit capacities for this role.
