99hatch- i agree with you for the most part, that is one way of the tongues. the bible gives to examples of speaking in tongues. the first is like you said, to give a message to someone or the church, this is where there will be a message given in tongues and someone through the spirit will interpret it. really cool stuff.

the second is when the Holy Spirit is making utterances for you. its praying for things you dont know to pray for. its your own personal line with God. some people are doing it for show tho. its very sad. thats why Jesus said not to be like those who pray loud for all to see and use many words to make themselves seem holy.
