Is There a Lingua Franca in Africa?

The only place that a oxling is likely to be really embraced would be among Native American and First Nations groups in the United States and Canada. None of those languages are currently used really as a lingua franca anywhere. They're all very small languages that are all very intensely identified with a particular ethnic group. We don't really have any other examples here. But I would encourage readers to give us more examples of these things.
