St Paul teaches, "When i am in the presence of the community i would rather say 5 words that mean something than 10K words in a tongue" (1Corinth 14:19).
Since in practice it is difficult to distinguish between the inspirations of the Holy Spirit and the instigations of a group leader, there should never be a call encouraging praying in tongues, and speaking in tongues should not take place unless there is an interpreter.
