Who are these "participants" you keep referring to?

Participants are the people collaborating to produce contracts and documents with LexPublica. They're lawyers, law students, legal experts, technical writers, editors, proofreaders, and keen laypeople. During our alpha release, we really only have a handful of participants. As LexPublica grows, though, we'll invite more and more participants to collaborate on more and more contracts until we're able to invite anyone and everyone to participate.
