In the rule “Mini Planet Expresses”, before “and a brief description of what services the Corporation provides”, add:-

its Trade,

And add after its second paragraph:-

The Trade of a Corporation may be None, Delivery, Production, Research or Exploration, and defaults to “None”. Certain Trades have Skill requirements, as listed below:-

• A Delivery Corporation must have one non-Drunk member with the Piloting Skill, and one member with the Accountancy Skill.
• A Production Corporation must have one member with the Bending Skill, and one member with the Accountancy Skill.
• A Research Corporation must have one member with the Science Skill, and one member with the Accountancy Skill.
• An Exploration Corporation must have one non-Drunk member with the Piloting Skill, and one member with the Science Skill.

If a Corporation does not meet the criteria for its Trade, any Earthling may change its Trade to “None”. If a member of a Corporation has a higher Leadership Skill than any other member of that Corporation, they may change the Trade of that Corporation at any time, provided that the Corporation meets the requirements listed above for its new Trade.
