Progress Report!
Part 1: Three missions completely finished, a few more need some tweaking, but it's minor. Still have about four missions remaining to FRED.
Part 2: One mission totally finished, two more are in the tweaking stage. The bulk of missions remain to be written.
Parts 3, 4: Story being written.
Website (which I've been devoting the bulk of my time to at this point): progressing, not sure how close to completion. Got some professional help with it, and it seems I'm just missing an index page... which neither I nor Spartan can figure out how to get working.
Barring unforseen problems, it should be up in a couple of weeks.
When I have one/two missions left to do, I'll put a call out for testers.
