"I am considering converting the races to the d20 system, and trying to convert the weapons.. anyone else interested, or willing to help......."
I really hate to be a stick-in-the-mud, but the Star Trek Questions and Mechanics forum is explicitly for "Information on the game mechanics, rules, and general ICON System questions," as stated in the main page of the Discussion Boards. As such, conversion TO the Icon system is on-topic, conversion FROM isn't. The Star Trek Narrator's Ready Room forum is primarily ICON-based, but discussions on running Star Trek RPGs of any stripe are nominally on topic so long as they don't push the ICON stuff out of the way. Of course, anything Star Trek related is on-topic in the Star Trek Chat forum, so I'm going to move this topic over there.
