Also you can request a guide to Purple Path behaviours (purple path? wizard? what is this, Oz? Not to worry – this becomes clear shortly). They have so far not actually emailed the paper to the address I furnished.
One possible reason: When asked “I agree not to share this doc with anyone. Instead, I will send friends to http://www.bit.ly/purplepath”, I checked ‘other’ and wrote that asking people not to share was rather a large commitment before they had seen the document. Whoops.
