Star Trek: Of Gods and Men
and Star Trek: Renegades
are fan films. That's not a bash on them, just a statement.
Trek's always been very lenient about this sort of thing, going all the way back to the fanzine movement in the 70's. I've read some wonderful stories from those, and enjoyed some recent fan productions, but they're still fan fiction and not official Star Trek. Fan films have become the modern day fanzine equivalent. It's incredibly cool to see Tim Russ and Walter Koenig playing their characters again, but they're still doing it in an unsanctioned production.
