I've been playing the demo for a while and I've got some questions.  
1)  Now that I have the Ministers turned on for what I want, how to I get my ships to respond to JUST the resupply minister?
2)  How can I upgrade existing ships, bases, and units to current designs?
3)  I forgot what my third question was, can you help me?    
 
  
Thanks in advance,
AtP
