Actually its not that big yet. Basically I've recently been GMing for the first time with the Star Trek RPG, and questions that I'm just not sure about come up. I tell myself I'll figure them out later, and never get to it.
So I'll probably come here to ask something that I'm a bit puzzled about and I don't have to actual book in my hand. One thing I was wondering about is recently my friend wanted to get Tier 2 abilities, he actually meets the requirments for one, but would he have to wait until he gets some 1000 XP to actually start advancing his character? Or can he do it pretty much anytime he wants as long as he meets the requirments?
