New pitcher - do you tell her the sitch?

I don't. For all the reasons already posted. The exception would be unless specifically directed to by the tournament UIC or director, or the rule code we're playing under.
If she came in with a count on the batter, I give it from behind the plate, just prior to indicating and verbalizing "Play" to make the ball live.
I do not give outs unless asked.
Like most of you who have replied, I have partners who do it when they have the plate. Drives me nuts. and the only thing I need my BU to be responsible for during a pitching change is counting the 5 warmup pitches if I'm occupied with a coach on substitution/lineup changes.
Besides, most of these teams, (esp. the TB teams), seem to have all these coaches who make it a career of watching every move the opposing team and the umpires make, surely one of them is more than capable of handling this particular detail.
