In regards to Orange Unity, which i spent a decent portions of my 2009 summer trying to solidify, I'd have to say IRON, TORN, R&R, TOP and FOK were major players trying to get things done. Unfortunately, I also think FOK was more concerned with LEO than OUT, but so be it. ODN mostly played lip service to it all, and Vanguard was nearly outright hostile to it all, if I remember correctly. Unfortunately, my AA at the time precluded me from working with FOK effectively, since a person in TORN utterly wrecked our FOK relations and then jumped ship, but I would have liked it if I had been able to work with them in retrospect. We (the Citrus Councilors) worked hard to get FnKa and tR into OUT and revitilize it.
It was a noble goal, but those with ulterior motives at heart wrecked it, IMO.
As for who got hit hardest, I'd have to say TORN did.
