I actually don't do too much, other than perhaps discuss whatever plotline their team would want to follow. Obviously, I'd have to do such a thing with someone, usually the "leader" of that team. As for missions, that's up to whomever's character makes it to the board first, or has an idea for a mission. This little thing is due to the fact that my older RPs had every RPer waiting for me to push them every second of the way. It eventually became too much for me, so yeah.
