After you find someone, you email to decide if you can both use Skype, Kakao or other free connection, set a time and start talking. As with any Internet contact, do not trust they are who they say they are. Do not tell them private information, such as when you will be away from home. Take your birth date and other personal information out of your Skype or Kakao profile. Another site has a good discussion of privacy for language learners and teachers.
Besides these well-organized sites, there are forums with long lists of people, not sorted by language, which are not as useful, though if you need a common language, you may find someone who just posted a request: ESL Teachers, Skype community, or Babelan.
