Following the example of OpenThesaurus.de we considered it good to include a customized version of jforum in the application, so that users can discuss matters related to synonyms etc.
Thanks a lot to Daniel Naber, author and maintainer of upstream OpenThesaurus project for releasing his customizations to jforum and to the people at http://code.google.com/p/jforum2/ for keeping up with maintainance of jforum (bug fixes, updated dependencies etc).
