I don't know if this outfit has a notation in the display sites thread.
Does LeanPub just look like another display site, or is there something more egregious going on? I'm not that impressed by crowd-sourced editing, and what they're doing here appears to violate first rights sales clauses, too. Why on earth would a writer want to post first drafts, anyway?
Anyone have any dealings with them yet? They're apparently a corporate sponsor of CampNaNo.
