What's the difference between passive and active Rp
[/quote]
PassiveRP is what you get when your character isn't performing any actions of note. It's quite useful when a time-skip is not an option.
ActiveRP is what you get when your character is performing an action of note. This is basically just standard role-playing.

There are a lot of terms I use in my style of role-playing that aren't used here.
