Hey, I am new to the community and love Discovery. I made a two civilian transports, one of them was a modified version of Seth Karlo's idea. I am at school now but will upload them in 3 or 4 hours.
(I drew them by hand since I don't have any progams to make them!)
They're supposed to be smaller transports, since they're civilian of course.
As nice as it is to hear my lack of talent has inspired someone, for now, I'm letting that idea go. It's too un-Freelancerish. By all means post your ideas, advice and help are very useful.
Finally, a good, free, 3D modelling program I use is Gmax. Not sure if its the best, but I like it. Google it.
