Ever since MFZ was mentioned on the Penny Arcade blog it has been growing in leaps and bounds. The Flickr group has doubled in membership, and there seem to be blogs and websites popping up all over the place. Seriously. Just plug "Mobile Frame Zero" into Google and see what happens. Anyway, here are a few sites for you so you don't have to do the whole Google thing.
Orion6 -- A new blog from Flickr member MittenNinja.
Mobile Frame Hangar -- A new website from Flickr member SchoonPine.
Mobile Frame Hangar Forums -- The corresponding forums for the above website.
Have fun surfing!
