Speak up, don't wither
When I first joined the SFB Staff I was very intimidated by some of it's members. It took me a little while to realize that, for example, just because a guy is a 2-star General is no reason not to give my opinion right alongside of his.
The circumstances of my life have resulted in my possessing an abnormal level of knowledge of "all things space ship". That is no reason not to give your opinion right alongside of mine. Your opinion is every bit as valid as mine. Even more so, really, because this game is not being made for SFB Staff members or life-long students of game design, it is being made for regular gamers. You are the target audience, not me, and as such your opinion is even more valuable to the designers of this game than mine is.
So learn this lesson sooner than I did and speak your mind even if it is the exact opposite of what I have said. Your opinion really is more valuable to the designers than mine is.
