A simple question of how to whisper to two people at the same time

Hello all, I didn't see how to do this, maybe I missed something easy - but, how do you whisper to two people at the same time? Specifically, I wish to be able to place into a macro something like /w Josh & GM. How can I do that? Thanks! Barry

If you will always whisper the same two people, you can make a macro that whispers to one, and then to the other (so two whisper lines in your macro) and have what it whispers be a text query that is the exact same query in each whisper, which when activated, will ask that query once, and use the result for both instances. If the whisper is always to the GM and one other, you can add a second query that asks which player it is going to, and have that output direct one of the whispers.

You can also make a new character and give both players control over it, so when you whisper to this "whisper character", both owners of the character heaes what he hears. This trick have been used to speak different languages in some games.

Thank you Aranador and Andreas J! Easier that I had first understood it to be.
