I agree with ack-ack. I have noticed that some players are completely unaware of the Help application. It's got all the aircraft performance figures in it, and all the ord requirements for destruction of ground targets.
As for training, I had very, very little. The reason was that the training in WB was on offer mid-evening US eastern time - 2am here. We would need trainers to cover more hours of the day. The WB trainers got free flying, so there was a great incentive to become a =trainer= in the $2/hour days. Now that we pay only 50¢/day, there would be less incentive to participate in a training programme.
