Collaboration and Social Features

You have content and resources at your fingertips. Now what? Liferay takes you to the next step and enables productive discussion around all your collective knowledge.


KnowledgeBase leverages collaboration functionality to provide a happy medium between centralized and distributed content creation; it is more structured than a wiki, but less formal than using a work-flow involved content management system.

While the articles themselves are meant to be provided by an administrator or site manager, end users can vote on whether these articles are helpful and make comments to them.


Build up and document important or interesting information as a community with Liferay's Wiki, which competes with standalone products in the robustness of feature set.

Each community gets its own Wiki with its own set of authorizations. Anyone with editing rights can quickly contribute information to these online topical encyclopedias.

Message Boards

Message Boards are a perfect solution for facilitating conversations around shared ideas within a department or project team, or for capturing and sharing the tacit knowledge of the workgroup.

Liferay offers views of message board activity statistics and recent posts and users can both subscribe to threads via RSS and reply to threads by email. Like all other portlets, Message Boards are secured by Liferay's granular system of authorizations which grants varying levels of control to different users.

  • Collabnet, the creators of SourceForge, used Liferay's Message Boards to build its Discussion Services functionality, part of CollabNet Enterprise Edition.


Liferay's Blogs provide the best features of modern blogging tools coupled with the benefits of the community-centric nature of Liferay Portal. They allow users to convey information and facilitate conversations around blogs directly in the context of a website, intranet, extranet, or social network.

Features include a user-friendly rich text editor, social bookmarking links, email notifications of blog replies, and an entry rating system. All blogs can be subscribed to via RSS and users can schedule entries to be published at specific times and dates.

Abuse Reporting

Liferay Portal offers an "Abuse Reporting" framework that allows community members and users to flag inappropriate content in our message boards, blogs, and any page within the portal. Developers can also leverage the associated framework for use in their own custom-developed applications


Subscribe to frequently read RSS feeds from message boards and blogs within the portal.

Activity Tracking

Keep tabs on the most recent activity on Liferay Blogs, Message Boards, Wiki and other tools. This information is displayed in "Recent Activity" portlets and on a Facebook-like Activity Wall.

  • See how Liferay is using Activity Tracking to serve its active open source community.

Instant Message

A friends list automatically displays the names of all other logged-in portal users. If you have something to say, just IM them. You also get familiar chat features like profile pictures and customized away messages. For your convenience, chat boxes stay at the bottom of your screen and follow you as you navigate through the portal while conversations remain secure behind your organization's firewall.


If you need to send an email, do it directly through the portal. A full AJAX-based webmail client with a sleek, user-friendly interface can be configured to interface with many popular IMAP email servers.

Shared Calendar

Community-based calendars that allow users to create, manage, search for events. Events can be shared across communities, and event reminders can be set up to alert users of upcoming events by email, IM, or SMS. Microformats and Calendaring support allow you to transfer calendar and user information via Web 2.0 standards.

Announcements & Alerts

Broadcast messages to different group of users whether they are simple announcements or "newsletter"-like in purpose.

Each user can control how they receive alerts: via portal-based web alert, SMS, Email or any additional delivery mechanisms configured by the portal administrator.

Dynamic Data Lists

Users can create custom lists of information that can be published as workflow-enabled forms. These forms can be shared with other users to capture information such as an RSVP, tasks tracking and managing issues.


Multiple choice polls can be created with this tool that also keeps track of votes. Many separate polls can be managed and a separate portlet can be configured to display a specific poll's results.

Social Equity

Social Equity is a brand new feature in Liferay version 6. It promotes the development of a dynamic social capital system by measuring the contribution and participation of a user and the information value of an asset. A person can gain equity by performing certain activities within communities, such as adding contributions (e.g., wikis, blogs), rating or commenting, and viewing content.

Tags & Categories

Liferay Portal enables users to create their own tags for any content, including blog entries, Wiki pages, and images. Tagging through administrator defined categories further enhances organizational and search capabilities.
