The Mixxer website connects language students with native speakers for language exchanges via Skype. A language exchange involves two people who are each learning the other's native language helping each other practice speaking. Users can create profiles, search for partners matching their language preferences, and practice writing with partners who can provide corrections. The site administrator explains that teachers can connect entire classes for exchanges by contacting the administrator, who can enable teacher search functions and help set up group video calls between classes at scheduled times.
