Lambda the Ultimate

Hi,

I've been pulling together a web site, somewhat inspired by LtU, focused on network protocol issues. I really like the way LtU is organized, and Imitation being the sincerest form of flattery and all that, I wonder if somebody can illuminate me about the platform that LtU is built on (looks like Drupal), modules in use, themes, and so forth? (I can't seem to find any kind of description document buried on the site.)

Thanks very much,

Miles Fidelman
