What I do: Move the beam slowly back and forth in front of them... as a friend calls it, the "yo... 'sup" signal. They'll look up at me at which point hand signals can begin.
I have had wild back-and-forth waves at me for things like "shark" or "octopus" etc - those can be mistaken for an emergency signal which can be annoying, but generally they're just excited signals. Additionally, when diving with someone who allows their light to hang under them (common with a pistol-grip light on a lanyard or retractor), the light will tend to hit me in the face with wild signals... again, annoying because my reaction is "emergency (jerk head up immediately and look for the problem)" but once I look up and see they're fine, I'm over it... I still never get used to the light in the face or wild waving though - always gives me a "jolt" which is annoying time after time on a dive.
One note on hand signals - remember that doing them infront of your body in our dark water can make them difficult to see. Moreover, doing them with your light pointed in your buddy's direction (even if not in their eyes), can make them difficult to see.
Good thread Ben!!
Please do the same, and ask those questions you've always wanted to know the answer to, but didn't ask for whatever reason. I though about dumping them all at once, but on second though I'll trickle them in one at a time. Please feel free to add your own! :occasion5: 
All responses appreciated.
