Anyway, I all ready have a few resources for Star Trek races I made from GCII, I will post the one's you don't all ready have.

Below is a sample of my GCII roster, though not the whole thing.
Here are all the Factions I can think of from Star Trek worth adding, though you've all ready added a number of them, I thought I'd keep the list as comprehensive as possible.

New Romulan Republic
The True Way
The Borg Collective
