New long-waited EasySocial features are finally here! Don't forget to update EasySocial application and check new bridge settings for EasySocial and settings in application 'User - phpBB Forum'.
Now you can create synonyms for terms. A synonym doesn't have own essential settings except Title, State and Language. Description is inherited from parent term. Synonyms are parsed in content like usual terms, but they don't have own pages and are always linked to parent term's individual page.
