That's right, you non-exlusive members aren't SHIT!
To be honest though, there's a lot of ways to get around this..
ie; make a crew, run it for like a week w/ somebody; then "leave" the crew so the other person is leader.
Upload a track, say its you; but in the description you put who it REALLY is...
etc etc. Still, this is better for the site. What I think you should do is completely shut down every crew; except for like 4-5. There's like 10,000 crews on here with maybe 20-30 active ones. By leaving 4-5 crews you make the site hella competitive and it becomes almost an honor to get invited into one of those crews.
