Hey, I was just wondering how to load my Cargo Ships up with resources from a planet?

You go to the fleet screen, select the cargoes, then click Continue. You select which planet you want to send the resources to, click Continue again. Then you select either Transport or Deploy (transport only sends the res, your ships go back to the original planet. Deploy makes the ships stay at the new planet as well) and then select the resources you want to send. You then click Continue again.

Ah thanks a lot, I seemed to of overlooked the resource input area.
