Man, it always seems the mod previews come in bunches. Got a couple on the way this week and was contacted for yet another today. As a result I'm currently installing a preview copy of Cold War Crisis for C&C: Zero Hour. It's shaping up to be a massive mod (currently over 1 GB - still downloading updates) so I'm excited to see what it plays like.
You'll get the official word on what it's like to play later on this week. Until then you can check out their profile. Stay tuned. Now I'm off to watch WALL-E tonight. Seeya!
