I'm gonna be really picky right now and say I really can't plot things out ahead of time. I guarantee I will get bored and frustrated if the characters' actions are forced to end up at a certain place. I have to be able to drop in plot points as they come, develop the plot as we go, and not know what's coming until we get to it. When the story calls for it, I'll drop in a clue or a walking Barbie doll or a newspaper article -- whatever would make sense or drive the story in that particular moment. You, of course, are free to do the same, and I hope you will. Just please don't storyboard ahead of time, and don't control my characters.

I know not a lot of people RP this way, and if you like plotting ahead that's awesome, but I can't. My philosophy is, do anything you want to do, drop in any plot device or alien monkey-llama or Jackie-is-a-cyborg wrench in the gears without a word ahead of time, and I'll gladly run with it. Have an idea and write it. Surprise me. I plan to go where the wind blows.

So if you want to bring in Mickey, go for it. If you have a crazy idea that would totally derail the plot, even better.
