Enact a new rule, “Convoys”:-

A Tribe may start a Convoy by posting a blog entry whose title begins “Convoy:”, if that Tribe does not already have an active Convoy. This is known as a Convoy Post, the Tribe who posted it is its Driver, and the entity it describes is a Convoy, which becomes active when posted.

A Convoy Post must contain an ordered list of three or more different Zones. This is known as its Convoy’s Route. The first Zone in the Route must belong to the Tribe that made the post. Each active Convoy has a Position, which defaults to the second Zone on its Route.

If the Position of a Convoy is an unoccupied Zone, the Driver of that Convoy may change its Position to the next Zone on its Route, by posting a comment to this effect.

If the Position of a Convoy is a Zone occupied by a Tribe, that Tribe may change the Convoy’s Position to the next Zone on its Route, by posting a comment to this effect.

If a Convoy’s Position is the final Zone of its Route, it ceases to be active.
