I'd like to extend a caution about what is generally referred to as 'god moding'.
Basically, please try to avoid controlling the actions of other characters. It's generally best to apply conditionals "If he turned around, he'd have to look down to see the diminutive Koemi" rather than "He turned around, saw no one, and had to look down to see Koemi".
One is a suggestion, the other deliberatingly taking control of the character. I know it's fairly innocent, but it's the kind of thing you never quite know if people will have a fit over or not.
"But you do it!" some might say, but then again, I'm the referee. It's my job to interpret your actions, and I generally do it in the interest of either making your characters look consistently professional and competent as well as move the story onward. If you didn't care for my narrative and credibility as arbiter you probably wouldn't be in my plot. =P
