Really, you probably don't even have to delve that deeply. College hockey itself is a niche sport; women's college hockey is a niche within a niche, and d3 women's hockey is smaller niche still. Frankly, I doubt the amount of ad money generated by most threads on any part of the boards covers the hosting and bandwidth costs of said threads - clickthru rates on ads are abysmal. Hence why USCHO has the "extra" subscription to garner more revenue.
Most game recap authors are students who also cover the team for their school paper. They sign-up to write for USCHO as well for a little more experience and exposure, if the school paper lets them. USCHO gets them a media credential if they can't get one through their school paper, but otherwise they don't get any compensation, travel or otherwise.
So, to get a game recap, you'd need a student who's also a game reporter for one of the teams who is also able to get to the game on his or her own dime.
