community.ubuntu.com has been launched on the last day on May. The community site helps users and developers to comunicate to each other and share their knowledge and experience.
“We’re very happy to announce that community.ubuntu.com is now online. It is the primary address for interested Ubuntu users to stay involved and get informed about what our community is doing.”
“If you want to help out and improve things, feel free to file bugs on the ubuntu-community-website project, where we keep track of things,” (source)
