I had just bought Sins: Rebellion a few days again, and i have decided to have a large game (10 players). Before i made it, i wanted to see what was new/different from the original (i went form Sins basic to Rebellion), and one thing I'm confused about:

The TEC Rebel's ability to call the pirates for help seemed interesting, but when i went to use the pirates (used the "attack" and "defend" buttons, and calling them with the broadcast center) they didn't respond. So i though "well maybe their under attack at their base" so i went there, and i found four groups of heavy-armed fleets of pirates. . .just sitting there. So what I want to know is: What are the conditions for the pirates to be able to help you? (because it seems the "calling" part doesn't work)
