The Gift of Tongues

We've certainly been moving through some challenging passages in 1 Corinthians in recent weeks, and this past Sunday's message on the gift of tongues was no exception. And while I realize we tackled a lot regarding what Paul says about tongues in chapter 14, I'm curious to hear what, if any, observations or experiences you've had with this gift. Specifically...

Have you ever been to a church where people spoke in tongues? What was that experience like? Was someone able to interpret what was being spoken? Were you and others encouraged and built up?
