Is giving or accepting advice in a team tournament acceptable?

I know that the help shouldnt come from some program or the like, but it seems to me, on first thought, that getting help from other team members should be okay?

Then I get to wondering.... couldnt that end up like playing against the best player from each team, if they were to be giving advice on moves and doubling etc?

But then again, who is to say that the advice from another player is always going to be good advice?

I think it is a team tournament, so let the team decide, the ultimate choice of what to do still always comes down to the person playing the game.
