I wonder if it might be worth giving Fred a category of his own in the "Teachers" section? His stuff seems legit to me and I quite like his approach so this might provide a mutually agreeable solution, Fred can post his material and hopefully get into some more public discussion of his take on things.
I don't have admin capabilities and I don't know if everyone would agree to the suggestion, after all most of us only know Fred via his 'hit n' run' posts [1] and we don't have a great deal of information from the guy. What's everyone else's thinking on this? If it's a viable suggestion, I can email Dan and ask him if it'd be possible.
[1] No offence, Fred, I hope you can appreciate why I'd describe your interactions so far using this choice of phrase.
