Bumping this because it's still my main creative outlet at the moment, and our small community (about as small as this one) is still growing. I definitely recommend a look if you or anyone you know is still into/interested in LEGO.

This project did get funded, quite successfully, and the rulebooks and kits for the Kickstarters are already coming out. My flickr page is still very active and you can see a lot of neat LEGO mech designs in the Mobile Frame Zero: Rapid Attack group on Flickr.

The majority of the activity is on the Mobile Frame Hangar forums, however. We discuss everything from the rules to creations ranging from mechs to vehicles to terrain.

Hrrrrg
How do you get good at LEGOs
Is LEGOs really a talent you have to train
Where do you get all these good pieces

Practice. Like anything else.
Yes. My early stuff is abominable. There's actually a thread on the Mobile Frame Hangar featuring a "Back then vs. Now" look at a lot of our work. Some of mine are there.
Most builders order parts individually on a community marketplace called Bricklink. I also hunt local retail clearance.

Be warned. Bricklink is very clunky to navigate. A light novel could be written explaining how to actually purchase pieces from it. Once you get used to it, though, buying pieces becomes easy.

grep, oh so unix ;o
Or Game Groomp.

But yeah, I'd be interested

EDIT [Also, what LDD's are out there, I'm staring at the LDD on the lego site and wondering if there are any 'better' items]
