Is it legal to receive coaching during a poker game?

Question

During a recent "bar game" of hold-em, one of the players at our table was being coached by someone not involved at the table. Is this legal? Should the tournament director have stopped it?

Answer 1

Coaching is NOT legal in poker.  The tournament director should definitely have stopped it!  One player to a hand!

Answer 2

I have to agree, that is very illegal. That player should have been disqualified if not stopped
