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.

BP Devolved Authority allows site administrators to devolve the ability to manage Groups, Activity, Members and Emails to other site members. For Xprofile information, you can also give specific individuals the ability to edit the xprofile fields for one or more named individuals.
BuddyPress has not traditionally allowed site administrators to grant authority to manage aspect of BuddyPress to users without ‘manage_options’ capability. This plugin changes that and allows each of the BP Components to be managed by site members so long as they have the ‘edit_posts’ capability.
Note that roles allowed to manage members should also have the ‘list_users’ capability, this allows the users list menu item to be displayed in the dashboard for that member.
The new feature – individual xprofile management delegation, creates a simple, secure delegation system whereby a privileged user (such as an administrator) can assign other registered BuddyPress members to be “delegates” for a given user. A delegate has the capability to view and edit Extended Profile (XProfile) fields for the delegated user. This is useful on sites where certain relationships exist between one user and another, such as legal guardianship by an adult over a child. Using delegation reduces the need to share passwords or log in to shared accounts.
Roles and capabilities for the delegated xprofile feature
This plugin uses the built-in capabilities system as part of WordPress core, along with core BuddyPress hooks (<code>bp_current_user_can</code>) to check for appropriate permissions, making it both simple to customize and as secure as WP and BP core code. The custom capabilities are:
<ul>
<li><code>edit_user_delegates</code> – Users with this capability can assign delegates for users they can edit (determined by <code>edit_users</code>).</li>
</ul>
Additionally, the following core capabilities are required:
<ul>
<li><code>list_users</code> – The delegation options implicitly enumerate all registered users, so a user must also have the <code>list_users</code> capability to be granted access to the Delegation user interface.</li>
<li><code>edit_users</code> – If you cannot <code>edit_users</code>, you cannot <code>edit_user_delegates</code>, either.</li>
</ul>
When this option is enabled, the admin can go to the users extended profile tab from the Dashboard>>Users list and choose to delegate authority over the xprofile data to another site member. That site member will then find in their Dashboard>>Users menu and option to see a list of “Devolved Profiles”.
Once the plugin is activated, visit the Settings>>BP Devolved Authority page to choose which roles can manage your BP Components.
This plugin needs BuddyPress to work.
