Can you tell me about the gift of tongues?

Can you tell me about the gift of tongues? My friends and I have had a few discussions on this and one point that was put forward is that it is something to be done in private as it can make others feel uneasy. Should it be done in private or is that just something people say?

Hi Rachel,
