Well, of course but it's not that you've to do anything. Take PhantomCruiser and SamuelEdwards for example. I just asked them permission to use them as crew for the mission, but they don't do anything.
So, if you want to be on the crew for the next mission, Sure! But don't expect that you have to do anything
I can't add it, sorry, its over 10 minutes long. What I thought of it? It should have had captions, its hard to keep track in my head especially with all the STS-xx-letter missions. The little bit at the end with the videos is nice, but unnecessary. The pictures weren't timed well with the music, giving it a monotonous pace. Anyways, that's my :2cents:
