If you distribute a Star Trek character, you don't NEED to specify non-commercial use. Anyone trying to make money out of Star Trek without permission from Paramount (?) is courting trouble. Yep, and if the default option is "Commercial or Non-commercial use" and neither the poster nor the Mods think to change it to say "Non-commercial use only", we could wind up in serious trouble because it would look like we were supporting trademark/copyright infringement.
