Hey... a gmail account is just as good as hotmail or yahoo account. However, if the company can't afford to pay your simulator training, then they may have bigger worries such as properly maintaining the aircraft, taking care of the crew whilst on the road and possibly meeting payroll. Then there's my old time goodie and favourite... "Put the room, fuel and ground handling on your credit card, and we'll reimburse you as soon as you get back"
.
Just food for thought.
