The main thing is for people to have fun. A lot of people, myself included, work long hours, have exams, or just other hobbies or commitments in general, and don't get to build as much as we'd like. Yes, it would be nice if we could get 100% of our members to participate in the GC, but if they can't that's fine too.
LC's in particular (including the CIC) have no effect on anyone except the individual member, so if people don't participate in them, then we shouldn't be too worried about it. I think we have a VERY strong faction, and I'm happy with the participation to-date. I also expect more people will have time as school wraps up in a few months, and other building competitions wind down.
Looking forward to seeing your entries! For someone like myself who doesn't get to build much, administrating and enjoying your MOCs is almost
as good as actually picking up the bricks
