The scope of work was integration and customization of the plugins BuddyPress and bbpress. We also customized the plugin ActivInsight Worksheet: 1. We added a possibility to play audio files by means of HTML5. 2. Implemented a feature to share the passed worksheet on FB and Twitter. 3. We made it possible to remove and print worksheets. 4. Using Buddypress API we developed the functionality to display the leaders who have a greatest amount of friends.
