I would like to know is there any module available in sitecore for community management application ( I could not find it in marketplace)? Or has any one implemented community management functionality in sitecore and if yes what third party tools/technology used in apart from Sitecore. I want to create a community management functionality where community members can share and exchange information ,articles, training materials , post and discussions etc with other members.
Building the entire functionality from scratch is my last option and before that is some free ware tool/ or module is available, I would like to try for that.
Any help or direction is appreciated.
