I've come across a few more MFZ related pages lately.
Iblitz Corporation -- A French blog that has a few entries about MFZ.
Dark Cloud -- This blog has recently started doing set reviews for MFZ.
MFDF -- A new dedicated alt-universe MFZ blog.
Arcadia: A Mobile Frame Zero World -- A new blog detailing the setting of one MFZ campaign.
MFZ Spain -- A page dedicated to bringing MFZ to Spanish speakers.
Lego FTW! -- Another pinterest page, this has a few creations that are a little large for MFZ but still look really neat.
Pimp My Bricks -- A tumblr page with a really unfortunate title. Some really nice choices for pictures though.
