- I have this pet theory which will no doubt be Jossed (Greenwalted?) sooner or later. That Wes's dad is not a Watcher, but someone wealthy and financially connected with the Council (if they have all that influence, at least some of the people involved must know who they are)--in short, some kind of profiteer in the war against the forces of evil.

- Even if your pet subject was "Jossed" by HBP (in other words, your theorizing was annihalated[sic] or impacted by a canon development) we'd love to have your archival works on HPInkPot - just select "pre-HBP" in the "when was this work written?" section.
