For the new enlistees, it would make sense to encourage the use of the training arena, website and tutorials before jumping into the MA.
Something like this pops up, when they log in and attempt to go straight to late war:
Thank you for joining Aces High, the most exciting virtual combat experience online!
A word of caution: there are many aspects to this game that take considerable time to learn. This is the real deal.
Plane and vehicle physics are modeled as realistically as possible and some long time players have many years of experience with them.
Don't be discouraged though, you can bring yourself up to speed much quicker by learning the basics.
The Aces High website (link) has a wealth of valuable information, including training and video tutorials to help you on your way.
Good luck and good hunting <S>
