Structure Definition . . .

Okay, I sent Boris a list of questions, because I didn't really know where they belonged or if they belonged. Based on his reply to me, I'm putting them here, in separate posts, since I believe they are different topics (but I may be wrong -- I'm sure someone will correct me, if I am).

Is there going to be some defined structure (read: documentation) as to what content is appropriate for the site or parts of the site and where the content should be placed?
