I'll try that out now.
There are several icon selection choices , friendly only ,no icons and normal icon.
Be sure to set it to normal icons so you see both the green and red guys!
As I said I'm usually in the TA after 9pm,come and check it out and don't be afraid to ask for help! Most fly as Bishops at A1 so don't worry about sides just choose Bish and you'll spawn by default at A1. Check the roster to see if I'm on or another trainer in in the training arena.
