The list you're looking for is actually under the announcements under at alliances & enemies.
You're right that alliances and enemies change minute by minute, that's why I try to keep the site as up to date as possible, changing it everyday for new alliances and enemies. Loric considers planets expendable, and I do as well to a point. NGNG is still around, but with Loric not on so much, its become misguided and chaotic.
