Entertainers can be recognized by the microphone icons above their heads.
Their job is to organize Smeet events. At some of these events, you can win special prizes and Fame Points. Even if you don't win, it's still worth checking out for the chance to meet other Smeeters and have fun!
Want to be an entertainer? If you think you know how to show people a good time, have a webcam and a microphone, email support [at] smeet [dot] com with a proposal for your event!
